Before this change guc_var_compare() cast the input arguments to
const struct config_generic *. That's not quite right however, as the input
on one side is often just a char * on one side.
Instead just use char *, the first field in config_generic.
This fixes a -Warray-bounds warning with some versions of gcc. While the

As commit ca4103025d stated, new partitions without a specified tablespace
should inherit the parent relation's tablespace. However, previously,

The current code can have pg_isready unexpectedly succeed if there is a

test until after a node has been created but before it starts, and then
use that node's port, so we are fairly sure there is nothing running on
the port.

Winsock only signals an FD_CLOSE event once if the other end of the
socket shuts down gracefully. Because each WaitLatchOrSocket() call
constructs and destroys a new event handle every time, with unlucky
timing we can lose it and hang. We get away with this only if the other
end disconnects non-gracefully, because FD_CLOSE is repeatedly signaled
in that case.
To fix this design flaw in our Windows socket support fundamentally,
we'd probably need to rearchitect it so that a single event handle
exists for the lifetime of a socket, or switch to completely different
multiplexing or async I/O APIs. That's going to be a bigger job
and probably wouldn't be back-patchable.
This brute force kludge closes the race by explicitly polling with
MSG_PEEK before sleeping.

When a partitioned table has an index that doesn't support a constraint,
but a partition has an equivalent index that does, then a DETACH
operation would misbehave: a crash in assertion-enabled systems (because
we fail to find the constraint in the parent that we expect to), or a
broken coninhcount value (-1) in production systems (because we blindly
believe that we've successfully detached the parent).
While we should reject an ATTACH of a partition with such an index, we
have failed to do so in existing releases, so adding an error in stable
releases might break the (unlikely) existing applications that rely on
this behavior. At this point I don't even want to reject them in
master, because it'd break pg_upgrade if such databases exist, and there
would be no easy way to fix existing databases without expensive index
rebuilds.
(Later on we could add ALTER TABLE ... ADD CONSTRAINT USING INDEX to
partitioned tables, which would allow the user to fix such patterns. At
that point we could add more restrictions to prevent the problem from
its root.)
Also, add a test case that leaves one table in this condition, so that
we can verify that pg_upgrade continues to work if we later decide to
change the policy on the master branch.

The slot synchronization failed because the local slot's (created during
slot synchronization) catalog_xmin on standby is ahead of remote slot.
This happens because the INSERT before slot synchronization results in the
generation of a new xid that could be replicated to the standby. Now
before the xmin of the physical slot on the primary catches up via
hot_standby_feedback, the test has created a logical slot that got some
prior value of catalog_xmin.
To fix this we could try to ensure that the physical slot's catalog_xmin
is caught up to latest value before creating a logical slot but we took a
simpler path to move the INSERT after synchronizing the logical slot.

When creating and initializing a logical slot, the restart_lsn is set
to the latest WAL insertion point (or the latest replay point on
standbys). Subsequently, WAL records are decoded from that point to
find the start point for extracting changes in the
DecodingContextFindStartpoint() function. Since the initial
restart_lsn could be in the middle of a transaction, the start point
must be a consistent point where we won't see the data for partial
transactions.
Previously, when not building a full snapshot, serialized snapshots
were restored, and the SnapBuild jumps to the consistent state even
while finding the start point. Consequently, the slot's restart_lsn
and confirmed_flush could be set to the middle of a transaction. This
could lead to various unexpected consequences. Specifically, there
were reports of logical decoding decoding partial transactions, and
assertion failures occurred because only subtransactions were decoded
without decoding their top-level transaction until decoding the commit
record.
To resolve this issue, the changes prevent restoring the serialized
snapshot and jumping to the consistent state while finding the start
point.
On v17 and HEAD, a flag indicating whether snapshot restores should be
skipped has been added to the SnapBuild struct, and SNAPBUILD_VERSION
has been bumpded.
On backbranches, the flag is stored in the LogicalDecodingContext
instead, preserving on-disk compatibility.

This back-patches HEAD commits 066e8ac6e, 6082b3d5d, e7192486d,
and 896cd266f into supported branches. Changes:
* Use xmlAddChildList not xmlAddChild in XMLSERIALIZE
(affects v16 and up only). This was a flat-out coding mistake
that we got away with due to lax checking in previous versions
of xmlAddChild.
* Use xmlParseInNodeContext not xmlParseBalancedChunkMemory.
This is to dodge a bug in xmlParseBalancedChunkMemory in libxm2
releases 2.13.0-2.13.2. While that bug is now fixed upstream and
will probably never be seen in any production-oriented distro, it is
currently a problem on some more-bleeding-edge-friendly platforms.
* Suppress "chunk is not well balanced" errors from libxml2,
unless it is the only error. This eliminates an error-reporting
discrepancy between 2.13 and older releases. This error is
almost always redundant with previous errors, if not flat-out
inappropriate, which is why 2.13 changed the behavior and why
nobody's likely to miss it.

For an inner_unique join, we always assume that the executor will stop
scanning for matches after the first match. Therefore, for a mergejoin
that is inner_unique and whose mergeclauses are sufficient to identify a
match, we set the skip_mark_restore flag to true, indicating that the
executor need not do mark/restore calls. However, merge-right-anti-join
did not get this memo and continues scanning the inner side for matches
after the first match. If there are duplicates in the outer scan, we
may incorrectly skip matching some inner tuples, which can lead to wrong
results.
Here we fix this issue by ensuring that merge-right-anti-join also
advances to next outer tuple after the first match in inner_unique
cases. This also saves cycles by avoiding unnecessary scanning of inner
tuples after the first match.
Although hash-right-anti-join does not suffer from this wrong results
issue, we apply the same change to it as well, to help save cycles for
the same reason.

isn't enough space to store the sentinel byte. If both sizes matched
exactly set_sentinel() would overwrite the first byte beyond the chunk
and then subsequent GenerationRealloc() calls could then fail the
Assert(chunk->requested_size < oldsize) check which is trying to ensure

macOS 15's SDK pulls in headers related to <regex.h> when we include
<xlocale.h>. This causes our own regex_t implementation to clash with

pg_ prefixes, but the macros and typenames did not.
Include <regex.h> explicitly on all POSIX systems, and fix everything
that breaks. Then we can prove that we are capable of fully hiding and
replacing the system regex API with our own.
1. Deal with standard-clobbering macros by undefining them all first.
POSIX says they are "symbolic constants". If they are macros, this
allows us to redefine them. If they are enums or variables, our macros
will hide them.
2. Deal with standard-clobbering types by giving our types pg_
prefixes, and then using macros to redirect xxx_t -> pg_xxx_t.
After including our "regex/regex.h", the system <regex.h> is hidden,
because we've replaced all the standard names. The PostgreSQL source
