Previously stats in the startup process would only get reported during
shutdown of the startup process. It has been that way for a long time, but
became a lot more noticeable with the new pg_stat_io view, which separates out
IO done by different backend types...
While replaying after every XLOG_RUNNING_XACTS isn't the prettiest approach,
it has the advantage of being quite easy. Given that we're well past feature
freeze...
It's not a problem that we don't report stats more frequently with
wal_level=minimal, in that case stats can't be read before the stats process
has shut down.
Besides the above, this commit also changes pgstat_report_stat() to acquire
the timestamp with GetCurrentTimestamp() instead of
GetCurrentTransactionStopTimestamp().
Thanks to Melih Mutlu, Kyotaro Horiguchi for prototypes of other approaches to
solving this issue.

Commit 927d9abb6 purported to make datetime() accept any string
that could be output for a datetime value by to_jsonb(). But it
overlooked the possibility of fractional seconds being present,
so that cases as simple as to_jsonb(now()) would defeat it.
Fix by adding formats that include ".US" to the list in
executeDateTimeMethod(). (Note that while this is nominally
microseconds, it'll do the right thing for fractions with
fewer than six digits.)
In passing, re-order the list to restore the datatype ordering
specified in its comment. The violation accidentally did not
break anything; but the next edit might be less lucky, so add
more comments.
Per report from Tim Field. Back-patch to v13 where datetime()
was added, like the previous patch.

We had left it icon-free since users won't achieve much by opening it
from Windows Explorer. Subsequent to that decision, Task Manager
started to show the icon. That shifts the balance in favor of attaching
the icon, so do so. No back-patch, but make this late addition to v16.

If we apply outer join identity 3 when relation C is a subquery
having lateral references to relation B, then the lateral references
within C continue to bear the original syntactically-correct
varnullingrels marks, but that won't match what is available from
the outer side of the nestloop. Compensate for that in
process_subquery_nestloop_params(). This is a slightly hacky fix,
but we certainly don't want to re-plan C in toto for each possible
outer join order, so there's not a lot of better alternatives.

- Commit 3eb77eba5a, which moved the pending ops queue from md.c to
sync.c, introduced a duplicate, unused 'pendingOpsCxt'
variable. (I'm surprised none of the compilers or static analysis
tools have complained about that.)
- Commit c2fe139c20 moved the 'synchronize_seqscans' variable and
introduced an extern declaration in tableam.h, making the one in
guc_tables.c unnecessary.
- Commit 6f0cf87872 removed the 'pgstat_temp_directory' GUC, but
forgot to remove the corresponding global variable.
- Commit 1b4e729eaa removed the 'pg_krb_realm' GUC, and its global
variable, but forgot the declaration in auth.h.
Spotted all these by reading the code.

isspace() can be locale-sensitive depending on the platform, causing
hstore to consider as whitespaces characters it should not see as such.
For example, U+0105, being decoded as 0xC4 0x85 in UTF-8, would be
discarded from the input given.
This problem is similar to 9ae2661, though it was missed that hstore
can also manipulate non-ASCII inputs, so replace the existing isspace()
calls with scanner_isspace().
This problem exists for a long time, so backpatch all the way down.

Split nbtree's _bt_getbuf function is two: code that read locks or write
locks existing pages remains in _bt_getbuf, while code that deals with
allocating new pages is moved to a new, dedicated function called
_bt_allocbuf. This simplifies most _bt_getbuf callers, since it is no
longer necessary for them to pass a heaprel argument. Many of the
changes to nbtree from commit 61b313e4 can be reverted. This minimizes
the divergence between HEAD/PostgreSQL 16 and earlier release branches.
_bt_allocbuf replaces the previous nbtree idiom of passing P_NEW to
_bt_getbuf. There are only 3 affected call sites, all of which continue
to pass a heaprel for recovery conflict purposes. Note that nbtree's
use of P_NEW was superficial; nbtree never actually relied on the P_NEW
code paths in bufmgr.c, so this change is strictly mechanical.
GiST already took the same approach; it has a dedicated function for
allocating new pages called gistNewBuffer(). That factor allowed commit
61b313e4 to make much more targeted changes to GiST.

While executing maintenance operations (ANALYZE, CLUSTER, REFRESH
MATERIALIZED VIEW, REINDEX, or VACUUM), set search_path to
'pg_catalog, pg_temp' to prevent inconsistent behavior.
Functions that are used for functional indexes, in index expressions,
or in materialized views and depend on a different search path must be

This change addresses a security risk introduced in commit 60684dd834,
where a role with MAINTAIN privileges on a table may be able to
escalate privileges to the table owner. That commit is not yet part of
any release, so no need to backpatch.

The same routine to check if a specific pattern can be found in the
server logs was copied over four different test scripts. This refactors
the whole to use a single routine located in PostgreSQL::Test::Cluster,
named log_contains, to grab the contents of the server logs and check
for a specific pattern.
On HEAD, the code previously used assumed that slurp_file() could not
handle an undefined offset, setting it to zero, but slurp_file() does
do an extra fseek() before retrieving the log contents only if an offset
is defined. In two places, the test was retrieving the full log
contents with slurp_file() after calling substr() to apply an offset,
ignoring that slurp_file() would be able to handle that.
Backpatch all the way down to ease the introduction of new tests that
could rely on the new routine.

A placeholder that references the outer join's relid in ph_eval_at
is logically "above" the join, and therefore we can't remove its
PlaceHolderInfo: it might still be used somewhere in the query.
This was not an issue pre-v16 because we failed to remove the join
at all in such cases. The new outer-join-aware-Var infrastructure
permits deducing that it's okay to remove the join, but then we
have to clean up correctly afterwards.

Apparently some extensions are in the habit of calling
ChangeVarNodes() with INDEX_VAR as the rt_index to replace.
That worked before 2489d76c4, at least as long as there were

because bms_is_member spits up. Add a test to avoid that.

pg_base64_enc_len() and its clones overestimated the output
length by up to 2 bytes, as a result of sloppy thinking about
where to divide. No callers require a precise estimate, so
this has no consequences worse than palloc'ing a byte or two
more than necessary. We might as well get it right though.
This bug is very ancient, dating to commit 79d78bb26 which
added encode.c. (The other instances were presumably copied
from there.) Still, it doesn't quite seem worth back-patching.

However, that commit failed to consider 32-bit MSVC builds where the

Commit fc22b6623b (generated columns) replaced ExecGetUpdatedCols() with
ExecGetAllUpdatedCols() in a couple places handling UPDATE (triggers and
lock mode). However, ExecGetUpdatedCols() did exec_rt_fetch() while
ExecGetAllUpdatedCols() also allocates memory through bms_union()
without paying attention to the memory context and happened to use the
long-lived ExecutorState, leaking the memory until the end of the query.
The amount of leaked memory is proportional to the number of (updated)
attributes, types of UPDATE triggers, and the number of processed rows
(which for UPDATE ... FROM ... may be much higher than updated rows).
Fixed by switching to the per-tuple context in GetAllUpdatedColumns().
This is fine for all in-core callers, but external callers may need to
copy the result. But we're not aware of any such callers.
Note the issue was introduced by fc22b6623b, but the macros were later
renamed by f50e888990.

The GUC settings lc_collate and lc_ctype are from a time when those
locale settings were cluster-global. When those locale settings were
made per-database (PG 8.4), the settings were kept as read-only. As
of PG 15, you can use ICU as the per-database locale provider, so
examining these settings is already less meaningful and possibly
confusing, since you need to look into pg_database to find out what is
really happening, and they would likely become fully obsolete in the
future anyway.

A new-style SQL function can contain a parse-time dependency
on a unique index, much as views and matviews can (such cases
arise from GROUP BY and ON CONFLICT clauses, for example).
To dump and restore such a function successfully, pg_dump must
postpone the function until after the unique index is created,
which will happen in the post-data part of the dump. Therefore
we have to remove the normal constraint that functions are
dumped in pre-data. Add code similar to the existing logic
that handles this for matviews. I added test cases for both
as well, since code coverage tests showed that we weren't
testing the matview logic.

When we're deleting a no-op LEFT JOIN from the query, we must remove
the join's joinclauses from surviving relations' joininfo lists.
The invention of "cloned" clauses in 2489d76c4 broke the logic for
that; it'd fail to remove clones that include OJ relids outside the
doomed join's min relid sets, which could happen if that join was
previously discovered to commute with some other join.
This accidentally failed to cause problems in the majority of cases,
because we'd never decide that such a cloned clause was evaluatable at
any surviving join. However, Richard Guo discovered a case where that
did happen, leading to "no relation entry for relid" errors later.
Also, adding assertions that a non-removed clause contains no Vars from
the doomed join exposes that there are quite a few existing regression
test cases where the problem happens but is accidentally not exposed.
The fix for this is just to include the target join's commute_above_r
and commute_below_l sets in the relid set we test against when
deciding whether a join clause is "pushed down" and thus not
removable.
While at it, do a little refactoring: the join's relid set can be
computed inside remove_rel_from_query rather than in the caller.
Patch by me; thanks to Richard Guo for review.
