The documentation for log_check() had the parameters in the wrong
order. Also while there, rename %parameters to %params to better
documentation for similar functions which use %params. Backpatch

After executing ALTER SUBSCRIPTION tap_sub SET PUBLICATION, we did not
wait for the new walsender process to restart. As a result, an INSERT
executed immediately after the ALTER could be decoded and skipped,
considering it is not part of any subscribed publication. And, the old
apply worker could also confirm the LSN of such an INSERT. This could
cause the replication to resume from a point after the INSERT. In such
cases, we miss the expected warning about the missing publication.
To fix this, ensure the walsender has restarted before continuing after
ALTER SUBSCRIPTION.

As complained about by Valgrind, in commit a379061a22a8 I failed to
realize that I was causing rd_att->constr->check to become allocated
when no CHECK constraints exist; previously it'd remain NULL. (This was
my bug, not the mentioned commit author's). Fix by making the
allocation conditional, and set ->check to NULL if unallocated.

Added by commit 042a66291b04, no backpatch needed.

This must be "return MemoryContextAllocationFailure(context, size, flags)"
instead. The effect of this oversight is that if we got a malloc
failure right here, the code would act as though MCXT_ALLOC_NO_OOM
had been specified, whether it was or not. That would likely lead
to a null-pointer-dereference crash at the unsuspecting call site.
Noted while messing with a patch to improve our Valgrind leak
detection support. Back-patch to v17 where this code came in.

This cleans up the code related to the testing infrastructure of AIO
that used injection points, switching the test code to use the new
facility for injection points added by 371f2db8b05e rather than tweaks
to pass and reset arguments to the callbacks run.
This removes all the dependencies to USE_INJECTION_POINTS in the AIO
code. pgaio_io_call_inj(), pgaio_inj_io_get() and pgaio_inj_cur_handle
are now gone.

The macros INJECTION_POINT() and INJECTION_POINT_CACHED() are extended
with an optional argument that can be passed down to the callback
attached when an injection point is run, giving to callbacks the
possibility to manipulate a stack state given by the caller. The
existing callbacks in modules injection_points and test_aio have their
declarations adjusted based on that.
da7226993fd4 (core AIO infrastructure) and 93bc3d75d8e1 (test_aio) and
been relying on a set of workarounds where a static variable called
pgaio_inj_cur_handle is used as runtime argument in the injection point
callbacks used by the AIO tests, in combination with a TRY/CATCH block
to reset the argument value. The infrastructure introduced in this
commit will be reused for the AIO tests, simplifying them.

A 'void *' argument suggests that the caller might pass an arbitrary
struct, which is appropriate for functions like libc's read/write, or
pq_sendbytes(). 'uint8 *' is more appropriate for byte arrays that
have no structure, like the cancellation keys or SCRAM tokens. Some
places used 'char *', but 'uint8 *' is better because 'char *' is
commonly used for null-terminated strings. Change code around SCRAM,
MD5 authentication, and cancellation key handling to follow these
conventions.

When creating an explicit Sort node for the outer path of a mergejoin,
we need to determine the number of presorted keys of the outer path to
decide whether explicit incremental sort can be applied. Currently,
this is done by repeatedly calling pathkeys_count_contained_in.
This patch caches the number of presorted outer pathkeys in MergePath,
allowing us to save several calls to pathkeys_count_contained_in. It
can be considered a complement to the changes in commit 828e94c9d.

When building a ForeignPath for a joinrel, if there's a possibility
that EvalPlanQual will be executed, we must identify a suitable path
for EPQ checks. If the outer or inner path of the chosen path is a
ForeignPath representing a pushed-down join, we replace it with its
fdw_outerpath to ensure that the EPQ check path consists entirely of
local joins.
If the chosen path is a MergePath, and its outer or inner path is a
ForeignPath that is not already well enough ordered, the MergePath
will have non-NIL outersortkeys or innersortkeys indicating the
desired ordering to be created by an explicit Sort node. If we then
replace the outer or inner path with its corresponding fdw_outerpath,
and that path is already sufficiently ordered, we end up in an
inconsistent state: the MergePath has non-NIL outersortkeys or
innersortkeys, and its input path is already properly ordered. This
inconsistency can result in an Assert failure or the addition of a
redundant Sort node.
To fix, check if the new outer or inner path of a MergePath is already
properly sorted, and set its outersortkeys or innersortkeys to NIL if
so.

A few places that access this catalog don't set up an active
snapshot before potentially accessing its TOAST table. However,
roname (the replication origin name) is the only varlena column, so
this is only a problem if the name requires out-of-line storage.
This commit removes its TOAST table to avoid needing to set up a
snapshot. It also places a limit on replication origin names so
that attempts to set long names will fail with a more user-friendly
error. Those chosen limit of 512 bytes should be sufficient to
avoid "row is too big" errors independent of BLCKSZ, but it should
also be lenient enough for all reasonable use-cases.

nbtree array index scans could fail to return matching tuples in rare
cases where the missed tuples cover key space that the scan's arrays
incorrectly indicate has already been read. These cases involved nearby
tuples with NULL values that were evaluated using a skip array key while
in pstate.forcenonrequired mode.
To fix, prevent forcenonrequired mode from prematurely advancing the
scan's array keys beyond key space that the scan has yet to read tuples
from: reset the scan's array keys (to the first elements in the current
scan direction) before the _bt_checkkeys call for pstate.finaltup. That
way _bt_checkkeys starts from a clean slate, which ensures that it will
call _bt_advance_array_keys (while passing it sktrig_required=true).
This reliably restores the invariant that the scan's arrays always
accurately track its progress through the index's key space (at least
when the scan is "between pages").
Oversight in commit 8a510275, which optimized nbtree search scan key
comparisons.

Be more conservative when performing a scheduled recheck of an nbtree
scan's array keys once on the next page, having set so->scanBehind: back
out of reading the page (perform another primitive scan instead) when
the next page's high key/finaltup has an untruncated prefix of matching
values and truncated suffix attributes associated with lower-order keys.
In other words, stop assuming that the lower-order keys have been
satisfied by the truncated suffix attributes in this context (only do so
when considering scheduling a recheck within _bt_advance_array_keys).
The new behavior is more logical: if the next page read after setting
so->scanBehind can only contain tuples that are themselves "behind the
scan", that's reason enough to cut our losses. In general, when we set
so->scanBehind, we only expect to perform one recheck on the next page
to make a final decision about whether or not to continue the current
primitive index scan. It seems unprincipled for the recheck to allow a
_bt_readpage to continue unless the scan's arrays will advance/unless
the page might actually contain relevant tuples.
In practice it is highly unlikely that things will line up like this
(the untruncated prefix of attribute values from the next page's high
key is seldom an exact match for their corresponding array's current
element following array advancement on the original/previous page).
That gives us all the more reason to keep things simple and consistent.
This was arguably an oversight in commit 9a2e2a285a, which improved
nbtree array primitive scan scheduling.

With GB18030 as source encoding, applications could crash the server via
SQL functions convert() or convert_from(). Applications themselves
could crash after passing unterminated GB18030 input to libpq functions
PQescapeLiteral(), PQescapeIdentifier(), PQescapeStringConn(), or
PQescapeString(). Extension code could crash by passing unterminated
GB18030 input to jsonapi.h functions. All those functions have been
intended to handle untrusted, unterminated input safely.
A crash required allocating the input such that the last byte of the
allocation was the last byte of a virtual memory page. Some malloc()
implementations take measures against that, making the SIGSEGV hard to
reach. Back-patch to v13 (all supported versions).
