Avoid testing tuple visibility without buffer lock in RI_FKey_check().

Despite the argumentation I wrote in commit 7a2fe85b0, it's unsafe to do
this, because in corner cases it's possible for HeapTupleSatisfiesSelf
to try to set hint bits on the target tuple; and at least since 8.2 we
have required the buffer content lock to be held while setting hint bits.
The added regression test exercises one such corner case. Unpatched, it
causes an assertion failure in assert-enabled builds, or otherwise would
cause a hint bit change in a buffer we don't hold lock on, which given
the right race condition could result in checksum failures or other data
consistency problems. The odds of a problem in the field are probably
pretty small, but nonetheless back-patch to all supported branches.

Fix EXPLAIN so that it doesn't emit invalid XML in corner cases.

With track_io_timing = on, EXPLAIN (ANALYZE, BUFFERS) will emit fields
named like "I/O Read Time". The slash makes that invalid as an XML
element name, so that adding FORMAT XML would produce invalid XML.
We already have code in there to translate spaces to dashes, so let's
generalize that to convert anything that isn't a valid XML name character,
viz letters, digits, hyphens, underscores, and periods. We could just
reject slashes, which would run a bit faster. But the fact that this went
unnoticed for so long doesn't give me a warm feeling that we'd notice the
next creative violation, so let's make it a permanent fix.
Reported by Markus Winand, though this isn't his initial patch proposal.
Back-patch to 9.2 where track_io_timing was added. The problem is only
latent in 9.1, so I don't feel a need to fix it there.

Rename Asia/Rangoon to Asia/Yangon, with a backward compatibility link.
The IANA crew continue their campaign to replace invented time zone
abbrevations with numeric GMT offsets. This update changes numerous zones
in Antarctica and the former Soviet Union, for instance Antarctica/Casey
now reports "+08" not "AWST" in the pg_timezone_names view. I kept these
abbreviations in the tznames/ data files, however, so that we will still
accept them for input. (We may want to start trimming those files someday,
but today is not that day.)
An exception is that since IANA no longer claims that "AMT" is in use
in Armenia for GMT+4, I replaced it in the Default file with GMT-4,
corresponding to Amazon Time which is in use in South America. It may be
that that meaning is also invented and IANA will drop it in a future
update; but for now, it seems silly to give pride of place to a meaning
not traceable to IANA over one that is.

Fix WAL-logging of FSM and VM truncation.
commit : 1c02ee314bc17ba0ff226c33a64935d02ff1208a

When a relation is truncated, it is important that the FSM is truncated as
well. Otherwise, after recovery, the FSM can return a page that has been
truncated away, leading to errors like:
ERROR: could not read block 28991 in file "base/16390/572026": read only 0
of 8192 bytes
We were using MarkBufferDirtyHint() to dirty the buffer holding the last
remaining page of the FSM, but during recovery, that might in fact not
dirty the page, and the FSM update might be lost.
To fix, use the stronger MarkBufferDirty() function. MarkBufferDirty()
requires us to do WAL-logging ourselves, to protect from a torn page, if
checksumming is enabled.
Also fix an oversight in visibilitymap_truncate: it also needs to WAL-log
when checksumming is enabled.

Fix cidin() to handle values above 2^31 platform-independently.

CommandId is declared as uint32, and values up to 4G are indeed legal.
cidout() handles them properly by treating the value as unsigned int.
But cidin() was just using atoi(), which has platform-dependent behavior
for values outside the range of signed int, as reported by Bart Lengkeek
in bug #14379. Use strtoul() instead, as xidin() does.
In passing, make some purely cosmetic changes to make xidin/xidout
look more like cidin/cidout; the former didn't have a monopoly on
best practice IMO.
Neither xidin nor cidin make any attempt to throw error for invalid input.
I didn't change that here, and am not sure it's worth worrying about
since neither is really a user-facing type. The point is just to ensure
that indubitably-valid inputs work as expected.
It's been like this for a long time, so back-patch to all supported
branches.

bitshiftright() and bitshiftleft() would recursively call each other
infinitely if the user passed INT_MIN for the shift amount, due to integer
overflow in negating the shift amount. To fix, clamp to -VARBITMAXLEN.
That doesn't change the results since any shift distance larger than the
input bit string's length produces an all-zeroes result.
Also fix some places that seemed inadequately paranoid about input typmods
exceeding VARBITMAXLEN. While a typmod accepted by anybit_typmodin() will
certainly be much less than that, at least some of these spots are
reachable with user-chosen integer values.

Fix another bug in merging of inherited CHECK constraints.

It's not good for an inherited child constraint to be marked connoinherit;
that would result in the constraint not propagating to grandchild tables,
if any are created later. The code mostly prevented this from happening
but there was one case that was missed.
This is somewhat related to commit e55a946a8, which also tightened checks
on constraint merging. Hence, back-patch to 9.2 like that one. This isn't
so much because there's a concrete feature-related reason to stop there,
as to avoid having more distinct behaviors than we have to in this area.

Fix two bugs in merging of inherited CHECK constraints.

Historically, we've allowed users to add a CHECK constraint to a child
table and then add an identical CHECK constraint to the parent. This
results in "merging" the two constraints so that the pre-existing
child constraint ends up with both conislocal = true and coninhcount > 0.
However, if you tried to do it in the other order, you got a duplicate
constraint error. This is problematic for pg_dump, which needs to issue
separated ADD CONSTRAINT commands in some cases, but has no good way to
ensure that the constraints will be added in the required order.
And it's more than a bit arbitrary, too. The goal of complaining about
duplicated ADD CONSTRAINT commands can be served if we reject the case of
adding a constraint when the existing one already has conislocal = true;
but if it has conislocal = false, let's just make the ADD CONSTRAINT set
conislocal = true. In this way, either order of adding the constraints
has the same end result.
Another problem was that the code allowed creation of a parent constraint
marked convalidated that is merged with a child constraint that is
!convalidated. In this case, an inheritance scan of the parent table could
emit some rows violating the constraint condition, which would be an
unexpected result given the marking of the parent constraint as validated.
Hence, forbid merging of constraints in this case. (Note: valid child and
not-valid parent seems fine, so continue to allow that.)
Per report from Benedikt Grundmann. Back-patch to 9.2 where we introduced
possibly-not-valid check constraints. The second bug obviously doesn't
apply before that, and I think the first doesn't either, because pg_dump
only gets into this situation when dealing with not-valid constraints.

Clear OpenSSL error queue after failed X509_STORE_load_locations() call.

Leaving the error in the error queue used to be harmless, because the
X509_STORE_load_locations() call used to be the last step in
initialize_SSL(), and we would clear the queue before the next
SSL_connect() call. But previous commit moved things around. The symptom
was that if a CRL file was not found, and one of the subsequent
initialization steps, like loading the client certificate or private key,
failed, we would incorrectly print the "no such file" error message from
the earlier X509_STORE_load_locations() call as the reason.

Don't share SSL_CTX between libpq connections.

There were several issues with the old coding:
1. There was a race condition, if two threads opened a connection at the
same time. We used a mutex around SSL_CTX_* calls, but that was not
enough, e.g. if one thread SSL_CTX_load_verify_locations() with one
path, and another thread set it with a different path, before the first
thread got to establish the connection.
2. Opening two different connections, with different sslrootcert settings,
seemed to fail outright with "SSL error: block type is not 01". Not sure
why.
3. We created the SSL object, before calling SSL_CTX_load_verify_locations
and SSL_CTX_use_certificate_chain_file on the SSL context. That was
wrong, because the options set on the SSL context are propagated to the
SSL object, when the SSL object is created. If they are set after the
SSL object has already been created, they won't take effect until the
next connection. (This is bug #14329)
At least some of these could've been fixed while still using a shared
context, but it would've been more complicated and error-prone. To keep
things simple, let's just use a separate SSL context for each connection,
and accept the overhead.
Backpatch to all supported versions.

Do ClosePostmasterPorts() earlier in SubPostmasterMain().

In standard Unix builds, postmaster child processes do ClosePostmasterPorts
immediately after InitPostmasterChild, that is almost immediately after
being spawned. This is important because we don't want children holding
open the postmaster's end of the postmaster death watch pipe.
However, in EXEC_BACKEND builds, SubPostmasterMain was postponing this
responsibility significantly, in order to make it slightly more convenient
to pass the right flag value to ClosePostmasterPorts. This is bad,
particularly seeing that process_shared_preload_libraries() might invoke
nearly-arbitrary code. Rearrange so that we do it as soon as we've
fetched the socket FDs via read_backend_variables().
Also move the comment explaining about randomize_va_space to before the
call of PGSharedMemoryReAttach, which is where it's relevant. The old
placement was appropriate when the reattach happened inside
CreateSharedMemoryAndSemaphores, but that was a long time ago.
Back-patch to 9.3; the patch doesn't apply cleanly before that, and
it doesn't seem worth a lot of effort given that we've had no actual

There is a small window between when the server closes out the existing
segment and the new one is created. Put a loop around the open call in
this case to make sure we wait for the new file to actually appear.

<sys/select.h> is required by POSIX.1-2001 to get the prototype of
select(2), but nearly no systems enforce that because older standards
let you get away with including some other headers. Recent OpenBSD
hacking has removed that frail touch of friendliness, however, which
broke some compiles; fix all the way back to 9.1 by adding the required
standard. Only vacuumdb.c was reported to fail, but it seems easier to
fix the whole lot in a fell swoop.

Faulty AND/OR nesting in the WHERE clause of getFuncs' SQL query led to
dumping range constructor functions if they are part of an extension
and we're in binary-upgrade mode. Actually, we don't want to dump them
separately even then, since CREATE TYPE AS RANGE will create the range's
constructor functions regardless. Per report from Andrew Dunstan.
It looks like this mistake was introduced by me, in commit b985d4877, in

Be sure to rewind the tuplestore read pointer in non-leader CTEScan nodes.

ExecInitCteScan supposed that it didn't have to do anything to the extra
tuplestore read pointer it gets from tuplestore_alloc_read_pointer.
However, it needs this read pointer to be positioned at the start of the
tuplestore, while tuplestore_alloc_read_pointer is actually defined as
cloning the current position of read pointer 0. In normal situations
that accidentally works because we initialize the whole plan tree at once,
before anything gets read. But it fails in an EvalPlanQual recheck, as
illustrated in bug #14328 from Dima Pavlov. To fix, just forcibly rewind
the pointer after tuplestore_alloc_read_pointer. The cost of doing so is
negligible unless the tuplestore is already in TSS_READFILE state, which
wouldn't happen in normal cases. We could consider altering tuplestore's
API to make that case cheaper, but that would make for a more invasive
back-patch and it doesn't seem worth it.
This has been broken probably for as long as we've had CTEs, so back-patch
to all supported branches.

Some experimentation with an older version of gcc showed that it is able
to determine whether "if (elevel_ >= ERROR)" is compile-time constant
if elevel_ is declared "const", but otherwise not so much. We had
accounted for that in ereport() but were too miserly with braces to
make it so in elog(). I don't know how many currently-interesting
compilers have the same quirk, but in case it will save some code
space, let's make sure that elog() is on the same footing as ereport()
for this purpose.
Back-patch to 9.3 where we introduced pg_unreachable() calls into

Fix locking a tuple updated by an aborted (sub)transaction

When heap_lock_tuple decides to follow the update chain, it tried to
also lock any version of the tuple that was created by an update that
was subsequently rolled back. This is pointless, since for all intents
and purposes that tuple exists no more; and moreover it causes
misbehavior, as reported independently by Marko Tiikkaja and Marti
Raudsepp: some SELECT FOR UPDATE/SHARE queries may fail to return
the tuples, and assertion-enabled builds crash.
Fix by having heap_lock_updated_tuple test the xmin and return success
immediately if the tuple was created by an aborted transaction.
The condition where tuples become invisible occurs when an updated tuple
chain is followed by heap_lock_updated_tuple, which reports the problem
as HeapTupleSelfUpdated to its caller heap_lock_tuple, which in turn
propagates that code outwards possibly leading the calling code
(ExecLockRows) to believe that the tuple exists no longer.
Backpatch to 9.3. Only on 9.5 and newer this leads to a visible
failure, because of commit 27846f02c176; before that, heap_lock_tuple
skips the whole dance when the tuple is already locked by the same
transaction, because of the ancient HeapTupleSatisfiesUpdate behavior.
Still, the buggy condition may also exist in more convoluted scenarios
involving concurrent transactions, so it seems safer to fix the bug in
the old branches too.

mdtruncate() forgot to FileClose() a segment's mdfd_vfd, when deleting
it. That lead to a fd.c handle to a truncated file being kept open until
backend exit.
The issue appears to have been introduced way back in 1a5c450f3024ac5,
before that the handle was closed inside FileUnlink().
The impact of this bug is limited - only VACUUM and ON COMMIT TRUNCATE
for temporary tables, truncate files in place (i.e. TRUNCATE itself is
not affected), and the relation has to be bigger than 1GB. The
consequences of a leaked fd.c handle aren't severe either.

Propagate that wording into a couple of places that were still using "zic"

Don't require dynamic timezone abbreviations to match underlying time zone.

Previously, we threw an error if a dynamic timezone abbreviation did not
match any abbreviation recorded in the referenced IANA time zone entry.
That seemed like a good consistency check at the time, but it turns out
that a number of the abbreviations in the IANA database are things that
Olson and crew made up out of whole cloth. Their current policy is to
remove such names in favor of using simple numeric offsets. Perhaps
unsurprisingly, a lot of these made-up abbreviations have varied in meaning
over time, which meant that our commit b2cbced9e and later changes made
them into dynamic abbreviations. So with newer IANA database versions
that don't mention these abbreviations at all, we fail, as reported in bug
#14307 from Neil Anderson. It's worse than just a few unused-in-the-wild
abbreviations not working, because the pg_timezone_abbrevs view stops
working altogether (since its underlying function tries to compute the
whole view result in one call).
We considered deleting these abbreviations from our abbreviations list, but
the problem with that is that we can't stay ahead of possible future IANA
changes. Instead, let's leave the abbreviations list alone, and treat any
"orphaned" dynamic abbreviation as just meaning the referenced time zone.
It will behave a bit differently than it used to, in that you can't any
longer override the zone's standard vs. daylight rule by using the "wrong"
abbreviation of a pair, but that's better than failing entirely. (Also,
this solution can be interpreted as adding a small new feature, which is
that any abbreviation a user wants can be defined as referencing a time
zone name.)
Back-patch to all supported branches, since this problem affects all
of them when using tzdata 2016f or newer.

This can't really work because standby_mode expects there to be more
WAL arriving, which there will not ever be because there's no WAL
receiver process to fetch it. Moreover, if standby_mode is on then
hot standby might also be turned on, causing even more strangeness
because that expects read-only sessions to be executing in parallel.

Previously pg_xlogdump failed to dump the contents of the WAL file
if the file starts with the continuation WAL record which spans

start reading from in that case.
This patch changes pg_xlogdump so that it can handle a continuation
WAL record which crosses a page boundary and find the valid record
to start reading from.

Commit f0c7b789a added a test case in case.sql that creates and then drops
both an '=' operator and the type it's for. Given the right timing, that
can cause a "cache lookup failed for type" failure in concurrent sessions,
which see the '=' operator as a potential match for '=' in a query, but
then the type is gone by the time they inquire into its properties.
It might be nice to make that behavior more robust someday, but as a

is never visible to other sessions. Like the previous commit, back-patch

ExecReScanAgg's check for whether it could re-use a previously calculated
hashtable neglected the possibility that the Agg node might reference
PARAM_EXEC Params that are not referenced by its input plan node. That's
okay if the Params are in upper tlist or qual expressions; but if one
appears in aggregate input expressions, then the hashtable contents need
to be recomputed when the Param's value changes.
To avoid unnecessary performance degradation in the case of a Param that
isn't within an aggregate input, add logic to the planner to determine
which Params are within aggregate inputs. This requires a new field in
struct Agg, but fortunately we never write plans to disk, so this isn't
an initdb-forcing change.
Per report from Jeevan Chalke. This has been broken since forever,

This is somewhat cosmetic, since as long as you know what you are looking
at, "10.0" is a serviceable substitute for "10". But there is a potential
for confusion between version numbers with minor numbers and those without
--- we don't want people asking "why is psql saying 10.0 when my server is
10.2". Therefore, back-patch as far as practical, which turns out to be
9.3. I could have redone the patch to use fprintf(stderr) in place of
psql_error(), but it seems more work than is warranted for branches that
will be EOL or nearly so by the time v10 comes out.
Although only psql seems to contain any code that needs this, I chose
to put the support function into fe_utils, since it seems likely we'll
need it in other client programs in future. (In 9.3-9.5, use dumputils.c,
the predecessor of fe_utils/string_utils.c.)
In HEAD, also fix the backend code that whines about loadable-library
version mismatch. I don't see much need to back-patch that.

something to do with the allowed range of a typmod-less numeric value,
but at least since 9.1 we've allowed, and documented that we allowed,
any value that would physically fit in the numeric storage format;
which is something over 100000 decimal digits, not 1000.
Hence, get rid of numeric_in()'s use of NUMERIC_MAX_PRECISION as a limit
on the allowed range of the exponent in scientific-format input. That was
especially silly in view of the fact that you can enter larger numbers as
long as you don't use 'e' to do it. Just constrain the value enough to
avoid localized overflow, and let make_result be the final arbiter of what
is too large. Likewise adjust ecpg's equivalent of this code.
Also get rid of numeric_recv()'s use of NUMERIC_MAX_PRECISION to limit the
number of base-NBASE digits it would accept. That created a dump/restore
hazard for binary COPY without doing anything useful; the wire-format
limit on number of digits (65535) is about as tight as we would want.
In HEAD, also get rid of pg_size_bytes()'s unnecessary intimacy with what
the numeric range limit is. That code doesn't exist in the back branches.
Per gripe from Aravind Kumar. Back-patch to all supported branches,
since they all contain the documentation claim about allowed range of
NUMERIC (cf commit cabf5d84b).

Back-patch 9.4-era commit 384f933046dc9e9a2b416f5f7b3be30b93587c63 into
the previous branches. Although that was only advertised as repairing a
problem with missed header-file dependencies, it turns out to also be
important for parallel make safety. The previous coding allowed two
independent make jobs to get launched concurrently in contrib/spi.
Normally this would be OK, because they are building independent targets;
but if --enable-depend is in use, it's unsafe, because one make run might
try to read a .deps file that the other one is in process of rewriting.
This is evidently the cause of buildfarm member francolin's recent failure
in the 9.2 branch. I believe this patch will result in only one subsidiary
make run, making it safe(r).

Fix inappropriate printing of never-measured times in EXPLAIN.

EXPLAIN (ANALYZE, TIMING OFF) would print an elapsed time of zero for
a trigger function, because no measurement has been taken but it printed
the field anyway. This isn't what EXPLAIN does elsewhere, so suppress it.
In the same vein, EXPLAIN (ANALYZE, BUFFERS) with non-text output format
would print buffer I/O timing numbers even when no measurement has been
taken because track_io_timing is off. That seems not per policy, either,
so change it.
Back-patch to 9.2 where these features were introduced.

Fix busted Assert for CREATE MATVIEW ... WITH NO DATA.

Commit 874fe3aea changed the command tag returned for CREATE MATVIEW/CREATE
TABLE AS ... WITH NO DATA, but missed that there was code in spi.c that
expected the command tag to always be "SELECT". Fortunately, the
consequence was only an Assert failure, so this oversight should have no
impact in production builds.
Since this code path was evidently un-exercised, add a regression test.
Per report from Shivam Saxena. Back-patch to 9.3, like the previous commit.

Previous contents of adminpack.sgml were rather far short of project norms.
Not to mention being outright wrong about the signature of pg_file_read().
