When a standby replays an XLOG_PARAMETER_CHANGE record that lowers
wal_level below logical, we invalidate all logical slots in hot
standby mode. However, if this record was replayed while not in hot
standby mode, logical slots could remain valid even after promotion,
potentially causing an assertion failure during WAL record decoding.
To fix this issue, this commit adds a check for hot_standby status
when restoring a logical replication slot on standbys. This check
ensures that logical slots are invalidated when they become
incompatible due to insufficient wal_level during recovery.
Backpatch to v16 where logical decoding on standby was introduced.

There is a race condition between "GRANT role" and "DROP ROLE",
which allows GRANT to install pg_auth_members entries that refer to
dropped roles. (Commit 6566133c5 prevented that for the grantor
field, but not for the granted or grantee roles.) We'll soon fix
that, at least in HEAD, but pg_dumpall needs to cope with the
situation in case of pre-existing inconsistency. As pg_dumpall
stands, it will emit invalid commands like 'GRANT foo TO ""',
which causes pg_upgrade to fail. Fix it to emit warnings and skip
those GRANTs, instead.
There was some discussion of removing the problem by changing
dumpRoleMembership's query to use JOIN not LEFT JOIN, but that
would result in silently ignoring such entries. It seems better
to produce a warning.
Pre-v16 branches already coped with dangling grantor OIDs by simply
omitting the GRANTED BY clause. I left that behavior as-is, although
it's somewhat inconsistent with the behavior of later branches.

ultimately means the relation was estimated to contain a single row.

Logical replication crashes if the subscriber's partitioned table
has a BRIN index. There are two independently blamable causes,
and this patch fixes both:
1. brininsertcleanup fails if called twice for the same IndexInfo,
because it half-destroys its BrinInsertState but leaves it still
linked from ii_AmCache. brininsert would also fail in that state,
so it's pretty hard to see any advantage to this coding. Fully
remove the BrinInsertState, instead, so that a new brininsert
call would create a new cache.
2. A logical replication subscriber sometimes does ExecOpenIndices
twice on the same ResultRelInfo, followed by doing ExecCloseIndices
twice; the second call reaches the brininsertcleanup bug. Quite
aside from tickling unexpected cases in aminsertcleanup methods,
this seems very wasteful, because the IndexInfos built in the
first ExecOpenIndices call are just lost during the second call,
and have to be rebuilt at possibly-nontrivial cost. We should
establish a coding rule that you don't do that.
The problematic coding is that when the target table is partitioned,
apply_handle_tuple_routing calls ExecFindPartition which does
ExecOpenIndices (and expects that ExecCleanupTupleRouting will
close the indexes again). Using the ResultRelInfo made by
ExecFindPartition, it calls apply_handle_delete_internal or
apply_handle_insert_internal, both of which think they need to do
ExecOpenIndices/ExecCloseIndices for themselves. They do in the main
non-partitioned code paths, but not here. The simplest fix is to pull
their ExecOpenIndices/ExecCloseIndices calls out and put them in the
call sites for the non-partitioned cases. (We could have refactored
apply_handle_update_internal similarly, but I did not do so today
because there's no bug there: the partitioned code path doesn't
call it.)
Also, remove the always-duplicative open/close calls within
apply_handle_tuple_routing itself.
Since brininsertcleanup and indeed the whole aminsertcleanup mechanism
are new in v17, there's no observable bug in older branches. A case
could be made for trying to avoid these duplicative open/close calls
in the older branches, but for now it seems not worth the trouble and
risk of new bugs.

This addresses various corner cases in BackgroundPsql:
- On windows stdout and stderr may arrive out of order, leading to errors not
being reported, or attributed to the wrong statement.
To fix, emit the "query-separation banner" on both stdout and stderr and
wait for both.
- Very occasionally the "query-separation banner" would not get removed, because
we waited until the banner arrived, but then replaced the banner plus
newline.
To fix, wait for banner and newline.
- For interactive psql replacing $banner\n is not sufficient, interactive psql
outputs \r\n.
- For interactive psql, where commands are echoed to stdout, the \echo
command, rather than its output, would be matched.
This would sometimes lead to output from the prior query, or wait_connect(),
being returned in the next command.
This also affected wait_connect(), leading to sometimes sending queries to
psql before the connection actually was established.
While debugging these issues I also found that it's hard to know whether a
query separation banner was attributed to the right query. Make that easier by
counting the queries each BackgroundPsql instance has emitted and include the
number in the banner.
Also emit psql stdout/stderr in query() and wait_connect() as Test::More
notes, without that it's rather hard to debug some issues in CI and buildfarm.
As this can cause issues not just to-be-added tests, but also existing ones,
backpatch the fix to all supported versions.

background_psql() in Cluster.pm gains the same "wait" parameter. The

Michael's original commit message:
A newline is not added at the end of an empty query result, causing the
banner of the hardcoded \echo to not be discarded. This would reflect
on scripts that expect an empty result by showing the "QUERY_SEPARATOR"
in the output returned back to the caller, which was confusing.
This commit changes BackgroundPsql::query() so as empty results are able
to work correctly, making the first newline before the banner optional,
bringing more flexibility.
Note that this change affects 037_invalid_database.pl, where three
queries generated an empty result, with the script relying on the data
from the hardcoded banner to exist in the expected output. These
queries are changed to use query_safe(), leading to a simpler script.
The author has also proposed a test in a different patch where empty
results would exist when using BackgroundPsql.

In try_partitionwise_join, we try to break down the join between two
partitioned relations into joins between matching partitions. To
achieve this, we iterate through each pair of partitions from the two
joining relations and create child join relations for them. To reduce
memory accumulation during each iteration, one step we take is freeing
the SpecialJoinInfos created for the child joins.
A child join's SpecialJoinInfo is a copy of the parent join's
SpecialJoinInfo, with some members being translated copies of their
counterparts in the parent. However, when freeing the bitmapset
members in a child join's SpecialJoinInfo, we failed to check whether
they were translated copies. As a result, we inadvertently freed the
members that were still in use by the parent SpecialJoinInfo, leading
to crashes when those freed members were accessed.
To fix, check if each member of the child join's SpecialJoinInfo is a
translated copy and free it only if that's the case. This requires
passing the parent join's SpecialJoinInfo as a parameter to
free_child_join_sjinfo.

Coverity complained that we weren't doing that, and it's right.
This fix just makes fmtIdEnc() honor the general convention that OOM
causes a PQExpBuffer to become marked "broken", without any immediate
error. In the pretty-unlikely case that we actually did hit OOM here,
the end result would be to return an empty string to the caller,
probably resulting in invalid SQL syntax in an issued command (if
nothing else went wrong, which is even more unlikely). It's tempting
to throw an "out of memory" error if the buffer becomes broken, but
there's not a lot of point in doing that only here and not in hundreds
of other PQExpBuffer-using places in pg_dump and similar callers.
The whole issue could do with some non-time-crunched redesign, perhaps.
This is a followup to the fixes for CVE-2025-1094, and should be
included if cherry-picking those fixes.
Instead of dropping the trailing byte(s) of an invalid or incomplete
multibyte character, replace only the first byte with a known-invalid
sequence, and process the rest normally. This seems less likely to
confuse incautious callers than the behavior adopted in 5dc1e42b4.
While we're at it, adjust PQescapeStringInternal to produce at most
one bleat about invalid multibyte characters per string. This
matches the behavior of PQescapeInternal, and avoids the risk of
producing tons of repetitive junk if a long string is simply given
in the wrong encoding.

That's bad, because it can lead to including input that wasn't intended to be

because it can lead to reading invalid memory if the input string is not null
terminated.

- Trailing incomplete multi-byte characters are handled sensibly

Functions which can report errors now return an error in more cases than
