The sentence in question gave readers the impression that vacuumdb
removes statistics for a period of time while analyzing, but it's
actually meant to convey that --analyze-in-stages temporarily
replaces existing statistics with ones generated with lower
statistics targets.

Recent discussions of the mechanisms used to manage global data have
raised concerns about their robustness and security. Rather than try
to deal with those concerns at a very late stage of the release cycle,
the conclusion is to revert these features and work on them for the
next release.

Logical replication requires reliable conflict detection to maintain data
consistency across nodes. To achieve this, we must prevent premature
removal of tuples deleted by other origins and their associated commit_ts
data by VACUUM, which could otherwise lead to incorrect conflict reporting
and resolution.
This patch introduces a mechanism to retain deleted tuples on the
subscriber during the application of concurrent transactions from remote
nodes. Retaining these tuples allows us to correctly ignore concurrent
updates to the same tuple. Without this, an UPDATE might be misinterpreted
as an INSERT during resolutions due to the absence of the original tuple.
Additionally, we ensure that origin metadata is not prematurely removed by
vacuum freeze, which is essential for detecting update_origin_differs and
delete_origin_differs conflicts.
To support this, a new replication slot named pg_conflict_detection is
created and maintained by the launcher on the subscriber. Each apply
worker tracks its own non-removable transaction ID, which the launcher
aggregates to determine the appropriate xmin for the slot, thereby
retaining necessary tuples.
Conflict information retention (deleted tuples and commit_ts) can be
enabled per subscription via the retain_conflict_info option. This is
disabled by default to avoid unnecessary overhead for configurations that
do not require conflict resolution or logging.
During upgrades, if any subscription on the old cluster has
retain_conflict_info enabled, a conflict detection slot will be created to
protect relevant tuples from deletion when the new cluster starts.
This is a foundational work to correctly detect update_deleted conflict
which will be done in a follow-up patch.

Avoid dependence on setlocale().
strcoll(), etc., are not called directly; all collation-sensitive
calls should go through pg_locale.c and use the appropriate
provider. By setting LC_COLLATE to C, we avoid accidentally depending
on libc behavior when using a different provider.
No behavior change in the backend, but it's possible that some
extensions will be affected. Such extensions should be updated to use
the pg_locale_t APIs.

The last_vacuum and vacuum_count fields in pg_stat_all_tables already

we are not back-patching this change to stable branches, as it is

This commit adds the possibility to specify a service file in a
connection string, using a new option called "servicefile". The parsing
of the service file happens so as things are done in this order of
priority:
- The servicefile connection option.
- Environment variable PGSERVICEFILE.
- Default path, depending on the HOME environment.
Note that in the last default case, we need to fill in "servicefile" for
the connection's PQconninfoOption to let clients know which service file
has been used for the connection. Some TAP tests are added, with a few
tweaks required for Windows when using URIs or connection option values,
for the location paths.

Previously, the idle_replication_slot_timeout parameter used minutes
as its unit, based on the assumption that values would typically exceed
one minute in production environments. However, this caused unexpected
behavior: specifying a value below 30 seconds would round down to 0,
effectively disabling the timeout. This could be surprising to users.
To allow finer-grained control and avoid such confusion, this commit changes
the unit of idle_replication_slot_timeout to seconds. Larger values can
still be specified easily using standard time suffixes, for example,
'24h' for 24 hours.

Increase the size of the "direct" histogram to 10K elements,
so that we can precisely track loop times up to 10 microseconds.
(Going further than that seems pretty uninteresting, even for
very old and slow machines.)
Relabel "Per loop time" as "Average loop time" for clarity.
Pre-zero the histogram arrays to make sure that they are loaded
into processor cache and any copy-on-write overhead has happened
before we enter the timing loop. Also use unlikely() to keep
the compiler from thinking that the clock-went-backwards case
is part of the hot loop. Neither of these hacks made a lot of
difference on my own machine, but they seem like they might help

Most of our platforms have better-than-microsecond timing resolution,
so the original definition of this program is getting less and less
useful. Make it report nanoseconds not microseconds. Also, add a
second output table that reports the exact observed timing durations,
up to a limit of 1024 ns; and be sure to report the largest observed
duration.
The documentation for this program included a lot of system-specific
details that now seem largely obsolete. Move all that text to the
PG wiki, where perhaps it will be easier to maintain and update.
Also, improve the TAP test so that it actually runs a short standard

While at it, silently accept ENFORCED if given.

The documentation previously stated that the wal_status column is NULL
if restart_lsn is NULL in the pg_replication_slots view. This is incorrect,
and wal_status can be "lost" even when restart_lsn is NULL.
This commit removes the incorrect description.
Back-patched to all supported versions.

The COPY FROM command now accepts a non-negative integer for the HEADER option,
allowing multiple header lines to be skipped. This is useful when the input
contains multi-line headers that should be ignored during data import.

The previous minimum was to maintain support for Python 3.5, but we
now require Python 3.6 anyway (commit 45363fca637), so that reason is
obsolete. A small raise to Meson 0.57 allows getting rid of a fair
amount of version conditionals and silences some future-deprecated
warnings.
With the version bump, the following deprecation warnings appeared and
are fixed:
WARNING: Project targets '>=0.57' but uses feature deprecated since '0.55.0': ExternalProgram.path. use ExternalProgram.full_path() instead
WARNING: Project targets '>=0.57' but uses feature deprecated since '0.56.0': meson.build_root. use meson.project_build_root() or meson.global_build_root() instead.
It turns out that meson 0.57.0 and 0.57.1 are buggy for our use, so
the minimum is actually set to 0.57.2. This is specific to this
version series; in the future we won't necessarily need to be this
precise.

There are different capitializations of "TOAST" around the
documentation and code. This just changes a few places that were more
obviously inconsistent with similar phrases elsewhere.

Switch MSVC to use the conforming preprocessor, using the
/Zc:preprocessor option.
This allows us to drop the alternative implementation of
VA_ARGS_NARGS() for the previous "traditional" preprocessor.
This also prepares the way for enabling C11 mode in the future, which
enables the conforming preprocessor by default.
This now requires Visual Studio 2019. The installation documentation
is adjusted accordingly.

This provides a convenient way to look up a database's OID. For
example, the query
SELECT * FROM pg_shdepend
WHERE dbid = (SELECT oid FROM pg_database
WHERE datname = current_database());
can now be simplified to
SELECT * FROM pg_shdepend
WHERE dbid = current_database()::regdatabase;
Like the regrole type, regdatabase has cluster-wide scope, so we
disallow regdatabase constants from appearing in stored
expressions.
Bumps catversion.

When postfix operators where dropped in 1ed6b8956, the CREATE OPERATOR
docs were not updated to make the RIGHTARG argument mandatory in the
grammar.
While at it, make the RIGHTARG docs more concise. Also, the operator
docs were mentioning "infix" in the introduction, while using "binary"
everywhere else.

Let the hacking begin ...

This commit renames the pg_recvlogical options --two-phase and
--failover to --enable-two-phase and --enable-failover, respectively.
The new names distinguish these enabling options from action options
like --start and --create-slot, while clearly indicating their purpose
to enable specific logical slot features.
The option --failover is new in PostgreSQL 18 (commit cf2655a9029), so
no compatibility break there. The option --two-phase has existed
since PostgreSQL 15 (commit cda03cfed6b), so for compatibility we keep
the old option name --two-phase around as deprecated.
Also note that pg_createsubscriber has acquired an --enable-two-phase
option, so this increases consistency across tools.
