Most callers of strerror() are removed from the backend code. The
remaining callers require special handling with a saved errno from a
previous system call. The frontend code still needs strerror() where
error states need to be handled outside of fprintf.
Note that pg_regress is not changed to use %m as the TAP output may
clobber errno, since those functions call fprintf() and friends before
evaluating the format string.
Support for %m in src/port/snprintf.c has been added in d6c55de1f9,
hence all the stable branches currently supported include it.

Commit f696c0cd5f caused a test failure in 002_pg_upgrade.pl, because
an earlier s/// operator caused qr// to no longer match the empty
string. Use qr/^$/ instead, which is a better test anyway, because we
expect the stderr to be empty.
Initially this appeared to be a perl bug, but per discussion, it seems
that it was a misunderstanding of how perl works: an empty pattern
uses the last successful pattern. Given how surprising that behavior
is to perl non-experts, we will need to look for similar problems
elsewhere and eliminate the use of empty patterns throughout the
code. For now, address this one instance to fix the buildfarm.

do_watch had some leftover logic for enabling siglongjmp out of

psql_cancel_callback), and do_watch no longer relies on it for
non-Windows, so let's drop it.
Also, when the user cancels \watch by pressing ^C, the Windows

seem very desirable, and it's not what happens on other platforms.

pg_constraint.conwithoutoverlaps was recently added to support primary
keys and unique constraints with the WITHOUT OVERLAPS clause. An
upcoming patch provides the foreign-key side of this functionality,
but the syntax there is different and uses the keyword PERIOD. It
would make sense to use the same pg_constraint field for both of
these, but then we should pick a more general name that conveys "this
constraint has a temporal/period-related feature". conperiod works
for that and is nicely compact. Changing this now avoids possibly
having to introduce versioning into clients. Note there are still
some "without overlaps" variables left, which deal specifically with
the parsing of the primary key/unique constraint feature.

There isn't a lot of user demand for AIX support, we have a bunch of
hacks to work around AIX-specific compiler bugs and idiosyncrasies,
and no one has stepped up to the plate to properly maintain it.
Remove support for AIX to get rid of that maintenance overhead. It's
still supported for stable versions.
The acute issue that triggered this decision was that after commit
8af2565248, the AIX buildfarm members have been hitting this
assertion:
TRAP: failed Assert("(uintptr_t) buffer == TYPEALIGN(PG_IO_ALIGN_SIZE, buffer)"), File: "md.c", Line: 472, PID: 2949728
Apperently the "pg_attribute_aligned(a)" attribute doesn't work on AIX
for values larger than PG_IO_ALIGN_SIZE, for a static const variable.
That could be worked around, but we decided to just drop the AIX support

For most purposes, multiranges act like dependent objects of the
associated range type: you can't create them separately or drop them
separately. This is like the way that autogenerated array types
behave. However, a couple of points were overlooked: array types
automatically track the ownership of their base type, and array types
do not have their own permissions but use those of the base type,
while multiranges didn't emulate those behaviors. This is fairly
broken, mainly because pg_dump doesn't think it needs to worry about
multiranges as separate objects, and thus it fails to dump/restore
ownership or permissions of multiranges.
There's no apparent value in letting a multirange diverge from
its parent's ownership or permissions, so let's make them act like
arrays in these respects. However, we continue to let multiranges
be renamed or moved to a different schema independently of their
parent, since that doesn't break anything.

Backpatch-through: v12
Commit 5b2f4afffe refactored find_other_exec() and in the process
created pipe_read_line() into a static routine for reading a single
line of output, aimed at reading version numbers. Commit a7e8ece41
later exposed it externally in order to read a postgresql.conf GUC
using "postgres -C ..". Further, f06b1c598 also made use of it for
reading a version string much like find_other_exec(). The internal
variable remained "pgver", even when used for other purposes.
Since the function requires passing a buffer and its size, and at
most size - 1 bytes will be read via fgets(), there is a truncation
risk when using this for reading GUCs (like how pg_rewind does,
though the risk in this case is marginal).
To keep this as generic functionality for reading a line from a pipe,
this refactors pipe_read_line() into returning an allocated buffer
containing all of the line to remove the risk of silent truncation.

Further fallout from commit 6ee26c6a4b. To keep code in sync and avoid
issues on older releases with different package names, simply use the
unqualified name like many other places in our code.
The latest buildfarm failures show that after the insert, we don't
actually wait long enough for WAL summarization to catch up, apparently
because the on disk state gets updated before the in-memory state, and
so by checking the on disk state to see whether we're caught up and then
the in-memory state to see where exactly how far we've progressed, we
can, if unlucky, derive an older value of summarized_lsn, messing up
the rest of the test.
Attempt to fix this by using pg_available_wal_summaries() everywhere in
the test and pg_get_wal_summarizer_state() nowhere.
Per buildfarm.
Make the new tuple larger than the old one so that it, hopefully, won't
manage to squeeze into leftover freespace on the same page. The test
is trying to verify that the UPDATE touches 2 pages, but if a HOT
update happens, then it doesn't.
Per buildfarm.
Analysis of buildfarm results showed that the code that was intended
to wait for the inserts performed by this test to complete did not
actually do so. Try to make that logic more robust.
Improve error checking elsewhere in the script, too, so that we
don't miss things like poll_query_until failing.
Along the way, fix a bit of pgindent damage introduced by commit
5ddf997347, which aimed to help us
debug the failures that this commit is trying to fix. It's making
the buildfarm sad.

This uses the replication commands introduced by commit 7329240437 to

If the failover option is set to true, the associated replication slots
(i.e. the main slot and the table sync slots) in the upstream database are
enabled to be synchronized to the standbys. Note that the capability to
sync the replication slots will be added in subsequent commits.
