the previous releases in the relevant branches. Those fixes did go out
in the previous releases, but missed getting documented.

Remove special cases for ETXTBSY from new fsync'ing logic.

The argument that this is a sufficiently-expected case to be silently
ignored seems pretty thin. Andres had brought it up back when we were
still considering that most fsync failures should be hard errors, and it
probably would be legit not to fail hard for ETXTBSY --- but the same is
true for EROFS and other cases, which is why we gave up on hard failures.
ETXTBSY is surely not a normal case, so logging the failure seems fine
from here.

Fix fsync-at-startup code to not treat errors as fatal.

Commit 2ce439f3379aed857517c8ce207485655000fc8e introduced a rather serious
regression, namely that if its scan of the data directory came across any
un-fsync-able files, it would fail and thereby prevent database startup.
Worse yet, symlinks to such files also caused the problem, which meant that
crash restart was guaranteed to fail on certain common installations such
as older Debian.
After discussion, we agreed that (1) failure to start is worse than any
consequence of not fsync'ing is likely to be, therefore treat all errors
in this code as nonfatal; (2) we should not chase symlinks other than
those that are expected to exist, namely pg_xlog/ and tablespace links
under pg_tblspc/. The latter restriction avoids possibly fsync'ing a
much larger part of the filesystem than intended, if the user has left
random symlinks hanging about in the data directory.
This commit takes care of that and also does some code beautification,
mainly moving the relevant code into fd.c, which seems a much better place
for it than xlog.c, and making sure that the conditional compilation for
the pre_sync_fname pass has something to do with whether pg_flush_data
works.
I also relocated the call site in xlog.c down a few lines; it seems a
bit silly to be doing this before ValidateXLOGDirectoryStructure().
The similar logic in initdb.c ought to be made to match this, but that
change is noncritical and will be dealt with separately.
Back-patch to all active branches, like the prior commit.

Fix portability issue in isolationtester grammar.

specparse.y and specscanner.l used "string" as a token name. Now, bison
likes to define each token name as a macro for the token code it assigns,
which means those names are basically off-limits for any other use within
the grammar file or included headers. So names as generic as "string" are
dangerous. This is what was causing the recent failures on protosciurus:
some versions of Solaris' sys/kstat.h use "string" as a field name.
With late-model bison we don't see this problem because the token macros
aren't defined till later (that is why castoroides didn't show the problem
even though it's on the same machine). But protosciurus uses bison 1.875
which defines the token macros up front.
This land mine has been there from day one; we'd have found it sooner
except that protosciurus wasn't trying to run the isolation tests till
recently.
To fix, rename the token to "string_literal" which is hopefully less
likely to collide with names used by system headers. Back-patch to
all branches containing the isolation tests.

Remove configure check prohibiting threaded libpython on OpenBSD.

According to recent tests, this case now works fine, so there's no reason
to reject it anymore. (Even if there are still some OpenBSD platforms
in the wild where it doesn't work, removing the check won't break any case
that worked before.)
We can actually remove the entire test that discovers whether libpython
is threaded, since without the OpenBSD case there's no need to know that
at all.
Per report from Davin Potts. Back-patch to all active branches.

Rename pg_shdepend.c's typedef "objectType" to SharedDependencyObjectType.
commit : 2e4c50137a6f96f84d804b41b355e125979e5494

The name objectType is widely used as a field name, and it's pure luck that
this conflict has not caused pgindent to go crazy before. It messed up
pg_audit.c pretty good though. Since pg_shdepend.c doesn't export this
typedef and only uses it in three places, changing that seems saner than
changing the field usages.
Back-patch because we're contemplating using the union of all branch
typedefs for future pgindent runs, so this won't fix anything if it
stays the same in back branches.

Back-patch libpq support for TLS versions beyond v1.
commit : 2c2c5f0e02b58d225385f5008fb797a90935cb06

Since 7.3.2, libpq has been coded in such a way that the only SSL protocol
it would allow was TLS v1. That approach is looking increasingly obsolete.
In commit 820f08cabdcbb899 we fixed it to allow TLS >= v1, but did not
back-patch the change at the time, partly out of caution and partly because
the question was confused by a contemporary server-side change to reject
the now-obsolete SSL protocol v3. 9.4 has now been out long enough that
it seems safe to assume the change is OK; hence, back-patch into 9.0-9.3.
(I also chose to back-patch some relevant comments added by commit
326e1d73c476a0b5, but did *not* change the server behavior; hence, pre-9.4
servers will continue to allow SSL v3, even though no remotely modern
client will request it.)
Per gripe from Jan Bilek.
