The documentation for the pg_authid system catalog and the
pg_shadow system view indicates that passwords might be stored in
cleartext, but that hasn't been possible for some time.

This commit renames the GUC log_lock_failure to log_lock_failures
to align with the existing similar setting log_lock_waits, which uses
the plural form. This improves naming consistency across related GUCs.

Commit 7406ab623f added a gist support function that we internally
refer to by the symbol GIST_STRATNUM_PROC. This translated from
"well-known" strategy numbers to opfamily-specific strategy numbers.
However, we later (commit 630f9a43ce) changed this to fit into
index-AM-level compare type mapping, so this function actually now
maps from compare type to opfamily-specific strategy numbers. So this
name is no longer fitting.
Moreover, the index AM level also supports the opposite, a function to
map from strategy number to compare type. This is currently not
supported in gist, but one might wonder what this function is supposed
to be called when it is added.
This patch changes the naming of the gist-level functionality to be
more in line with the index-AM-level functionality. This makes sense
because these are essentially the same thing on different levels.
This also changes the names of the externally visible functions that
are provided for use as such a support function.

Previously, postgres_fdw always 1) opened a remote transaction in READ
WRITE mode even when the local transaction was READ ONLY, causing a READ
ONLY transaction using it that references a foreign table mapped to a
remote view executing a volatile function to write in the remote side,
and 2) opened the remote transaction in NOT DEFERRABLE mode even when
the local transaction was DEFERRABLE, causing a SERIALIZABLE READ ONLY
DEFERRABLE transaction using it to abort due to a serialization failure
in the remote side.
To avoid these, modify postgres_fdw to open a remote transaction in the
same access/deferrable modes as the local transaction. This commit also
modifies it to open a remote subtransaction in the same access mode as
the local subtransaction.
Although these issues exist since the introduction of postgres_fdw,
there have been no reports from the field. So it seems fine to just fix
them in master only.

To improve the usability of logical replication examples, we need to
enable bulk copy-pasting of DML/DDL series.
Currently, output command tags and prompts disrupt this workflow. While
prompts are typically removed, converting them to comments is acceptable
here, given the multi-server context.
Additionally, ensure all examples containing operators like < and > are
wrapped in CDATA blocks to guarantee correct rendering and consistency
with other places.

The documentation for exported snapshots in logical decoding previously
stated that snapshot creation may fail on a hot standby. This is no longer
accurate, as snapshot exporting on standbys has been supported since
PostgreSQL 10. This commit removes the outdated description.
Additionally, the docs referred to the NOEXPORT_SNAPSHOT option to
suppress snapshot exporting in CREATE_REPLICATION_SLOT. However,
since PostgreSQL 15, NOEXPORT_SNAPSHOT is considered legacy syntax
and retained only for backward compatibility. This commit updates
the documentation for v15 and later to use the modern equivalent:
SNAPSHOT 'nothing'. The older syntax is preserved in documentation for
v14 and earlier.
Back-patched to all supported branches.

9219093cab modularized log_connections output to allow more
granular control over which aspects of connection establishment are
logged. It converted the boolean log_connections GUC into a list of strings
and deprecated previously supported boolean-like values on, off, true,
false, 1, 0, yes, and no. Those values still work, but they are
supported mainly for backwards compatability. As such, documented
examples of log_connections should not use these deprecated values.
Update references in the docs to deprecated log_connections values. Many
of the tests use log_connections. This commit also updates the tests to
use the new values of log_connections. In some of the tests, the updated
log_connections value covers a narrower set of aspects (e.g. the
'authentication' aspect in the tests in src/test/authentication and the
'receipt' aspect in src/test/postmaster). In other cases, the new value
for log_connections is a superset of the previous included aspects (e.g.
'all' in src/test/kerberos/t/001_auth.pl).

As pointed out by Tom Lane, the patch introduced fragile and invasive
design around plan invalidation handling when locking of prunable
partitions was deferred from plancache.c to the executor. In
particular, it violated assumptions about CachedPlan immutability and
altered executor APIs in ways that are difficult to justify given the
added complexity and overhead.
This also removes the firstResultRels field added to PlannedStmt in
commit 28317de72, which was intended to support deferred locking of
certain ModifyTable result relations.

Commit db6a4a985b categorized md5_password_warnings as an
authentication setting, and the placement in postgresql.conf.sample
matches that, but in the documentation it ended up under logging
settings, which isn't unreasonable but inconsistent. This moves the
documentation chunk to authentication settings as well.
Invalid indexes are suffixed with "_ccnew" or "_ccold". The
documentation missed to mention the initial underscore.
ChooseRelationName() may also append an extra number if indexes with a
similar name already exist; let's add a note about that too.

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.
