Some otherwise Posix-compatible filesystems do not support symlinks. To support this allow symlinks to be disabled.

Nothing changed in PostgreSQL before 18.0 so the support is no longer experimental.

These cases were either missed in 0dabf88e or added afterwards.

On recent versions of Docker it is not necessary to specify the architecture of the require image. The --platform option takes care of it.  
  
Rebuild test images that were modified by this change.

This test was removed in c64cd8e0 because it was taking too long to be scheduled, which held up testing.  
  
Now that Github Actions supports aarch64 move the test there.

Similar to adc5e5b23, STRDEF assignment to reason can be out of scope, which may lead to either garbage in the log message or a crash with SIGSEGV.  
  
Fix by using simple char * constants for the reason.

Use strNewZ() so the value persists past the block where it is assigned.

The SFTP storage driver did not set the pathSync method but had logic to see if pathSync was set. This led to some tortured tests since pathSync had to be injected into the interface after the storage object had been created.  
  
Remove the pathSync parameter from storageWriteSftpNew() and also remove related tests.

These timeouts were nested, i.e. an error in the socket connection would also retry in the TLS and HTTP layers. This led to a multiplying effect such that it took nine minutes to fully timeout with the default io-timeout of 60 seconds.  
  
A fix for this was attempted in 5314dbff but it reduced retries by too much and had to be reverted in fa5b2d44.  
  
Instead fix by moving connection attempts to the lower layer (e.g. TLS -> socket) out of the exception block but leave it within the retry loop. So, for example, if the socket connection fails after retries then the error will not be retried by TLS. But if the TLS session fails the socket will be reconnected.

The STRDEF definition of plural is out of scope in the error message just below it, which may lead to either garbage in the log message or a crash with SIGSEGV.  
  
This is particularly visible with pg_tde, which encrypts tables: if pgbackrest is run with checksum enabled, it tries to emit this message for all encrypted files.  
  
Fix by using simple char * constants in the error message.

Rebuild all containers to get the most recent versions of PostgreSQL.  
  
Update the Debian repository install to match current recommendations. This has already been done for the documentation in fcd00a45.

HTTP client errors 408 and 429 were not being retried but there seems to be some benefit to doing so.  
  
408 has only been seen once and in that case the server was returning 400 (with Request Timeout in the response body) but it seems worth doing since this could happen during times of high congestion. Requests are not sent until request content is ready so there is not much else to be done to handle this error.  
  
429 has been seen occasionally in the past but now seems to be common on Cloudflare R2. Ideally we would have a large initial back off here but it is not clear that is worth it at this time. The existing Fibonacci back off should be enough to allow operations to proceed if possible during the configured timeout.
