This commit adds support for REINDEX in event triggers, making this
command react for the events ddl_command_start and ddl_command_end. The
indexes rebuilt are collected with the ReindexStmt emitted by the
caller, for the concurrent and non-concurrent paths.
Thanks to that, it is possible to know a full list of the indexes that a
single REINDEX command has worked on.

The wording changed here comes from 991bfe11d2, when the only way to
trigger a promotion was with a trigger file. There are more options to
achieve this operation these days, like the SQL function pg_promote() or
the command `pg_ctl promote`, so it is confusing to assume that only a
trigger file is able to do the work.
Note also that promote_trigger_file has been removed as of cd4329d939
in 16~.

Since these tests are very expensive the entire suite is disabled by

When there is a need to filter multiple tables with include and/or exclude
options it's quite possible to run into the limitations of the commandline.
This adds a --filter=FILENAME feature to pg_dump, pg_dumpall and pg_restore
which is used to supply a file containing object exclude/include commands
which work just like their commandline counterparts. The format of the file
is one command per row like:
<command> <object> <objectpattern>
<command> can be "include" or "exclude", <object> can be table_data, index
table_data_and_children, database, extension, foreign_data, function, table
schema, table_and_children or trigger.
This patch has gone through many revisions and design changes over a long
period of time, the list of reviewers reflect reviewers of some version of
the patch, not necessarily the final version.

This patch adds 'stats_since' and 'minmax_stats_since' columns to the
pg_stat_statements view and pg_stat_statements() function. The new min/max
reset mode for the pg_stat_stetments_reset() function is controlled by the
parameter minmax_only.
'stat_since' column is populated with the current timestamp when a new
statement is added to the pg_stat_statements hashtable. It provides clean
information about statistics collection time intervals for each statement.
Besides it can be used by sampling solutions to detect situations when a
statement was evicted and stored again between samples.
Such a sampling solution could derive any pg_stat_statements statistic values
for an interval between two samples with the exception of all min/max
statistics. To address this issue this patch adds the ability to reset
min/max statistics independently of the statement reset using the new
minmax_only parameter of the pg_stat_statements_reset(userid oid, dbid oid,
queryid bigint, minmax_only boolean) function. The timestamp of such reset
is stored in the minmax_stats_since field for each statement.
pg_stat_statements_reset() function now returns the timestamp of a reset as the
result.

these structures only once, and reuses them for all inserts in the same

This also introduces an optional AM callback "aminsertcleanup" that
allows performing custom cleanup in case simply pfree-ing ii_AmCache is
not sufficient (which is the case when the cache contains TupleDesc,

This commit log messages (at LOG level when log_replication_commands is
set, otherwise at DEBUG1 level) when walsenders acquire and release
replication slots. These messages help to know the lifetime of a
replication slot - one can know how long a streaming standby, logical
subscriber, or replication slot consumer is down. These messages will be
useful on production servers to debug and analyze inactive replication
slots.
Note that these messages are emitted only for walsenders but not for
backends. This is because walsenders are the ones that typically hold
replication slots for longer durations, unlike backends which hold them
for executing replication related functions.

Currently important build targets are somewhat hard to discover. This commit
documents important meson build targets in the sgml documentation. But it's
awkward to have to lookup build targets in the docs when hacking, so this also
adds a 'help' target, printing out the same information. To avoid having to
duplicate information in two places, generate both docbook and interactive

A subsequent commit will overhaul the documentation for the documentation

While at it, move all target in doc/src/sgml/Makefile up to just after the
default "html" target, and add a comment explaining "all" is *not* the default

taken to imply that the SELECT privilege is required on all columns of

referred to by conditions or expressions in the MERGE command. Re-word
it to make that a little clearer, and mention expressions as well as
conditions.
Also, add a glossary entry for MERGE, and nearby on the glossary page,
mention MERGE in the list of commands that cannot update a

Currently, pg_stat_reset_shared() cannot reset the counters in the view
pg_stat_slru even if it is a type of shared stats. This patch adds
support for a new value in pg_stat_reset_shared(), called "slru", able
to do that. Note that pg_stat_reset_shared(NULL) also resets SLRU
counters.
There may be a point in removing pg_stat_reset_slru() that was
introduced in 28cac71bd3 (v13~) as the new option overlaps with this
function, but we would lose the ability to reset individual SLRU
counters. This is left for future reconsideration.

This adds support for infinity to the interval data type, using the
same input/output representation as the other date/time data types
that support infinity. This allows various arithmetic operations on
infinite dates, timestamps and intervals.
The new values are represented by setting all fields of the interval
to INT32/64_MIN for -infinity, and INT32/64_MAX for +infinity. This
ensures that they compare as less/greater than all other interval
values, without the need for any special-case comparison code.
Note that, since those 2 values were formerly accepted as legal finite
intervals, pg_upgrade and dump/restore from an old database will turn
them from finite to infinite intervals. That seems OK, since those
exact values should be extremely rare in practice, and they are
outside the documented range supported by the interval type, which
gives us a certain amount of leeway.

pg_stat_reset_slru currently requires an input argument, either:
- NULL to reset the SLRU counters of everything.
- A specific value to reset a single SLRU cache.
This commit adds support for a new pattern: pg_stat_reset_slru without
any argument works the same way as pg_stat_reset_slru(NULL), relying on
a DEFAULT in the function definition to handle this case. This makes
the function more consistent with 23c8c0c8f4.

Default privileges are represented as NULL::aclitem[] in catalog ACL
columns, while revoking all privileges leaves an empty aclitem[].
These two cases used to produce identical output in psql meta-commands
like \dp. Using something like "\pset null '(default)'" as a
workaround for spotting the difference did not work, because null
values were always displayed as empty strings by describe.c's
meta-commands.
This patch improves that with two changes:
1. Print "(none)" for empty privileges so that the user is able to
distinguish them from default privileges, even without special
workarounds.
2. Remove the special handling of null values in describe.c,
so that "\pset null" is honored like everywhere else.
(This affects all output from these commands, not only ACLs.)
The privileges shown by \dconfig+ and \ddp as well as the column
privileges shown by \dp are not affected by change #1, because the
respective aclitem[] is reset to NULL or deleted from the catalog
instead of leaving an empty array.
