As demonstrated by David Johnston, the Memoize cache hit ratio calculation
wasn't quite correct.
This change only affects the estimated hit ratio when the estimated number
of entries to cache is estimated not to fit inside the cache. For
example, if we expect 2000 distinct cache key values and only expect to be
able to cache 1000 of those at once due to memory constraints, with an
estimate of 10000 calls, if we could store all entries then the hit ratio
should be 80% to account for the first 2000 of the 10000 calls to be a
cache miss due to the value not being cached yet. If we can only store
1000 entries for each of the 2000 distinct possible values at once then
the 80% should be reduced by half to make the final estimate of 40%.
Previously, the calculation would have produced an estimated hit ratio of
30%, which wasn't correct.
Apply to master only so as not to destabilize plans in the back branches.

The check for the number of roles in the target cluster for an upgrade
selects the existing roles and performs a COUNT(*) over the result. A
value of one is the expected query result value indicating that only
the install user is present in the new cluster. The result was converted
with the function for converting a string containing an Oid into a numeric,
which avoids potential overflow but makes the code less readable since
it's not actually an Oid at all.

With unlucky timing and parallel_leader_participation=off (not the
default), PHJ could attempt to access per-batch shared state just as it
was being freed. There was code intended to prevent that by checking
for a cleared pointer, but it was racy. Fix, by introducing an extra
barrier phase. The new phase PHJ_BUILD_RUNNING means that it's safe to
access the per-batch state to find a batch to help with, and
PHJ_BUILD_DONE means that it is too late. The last to detach will free
the array of per-batch state as before, but now it will also atomically
advance the phase, so that late attachers can avoid the hazard. This
mirrors the way per-batch hash tables are freed (see phases
PHJ_BATCH_PROBING and PHJ_BATCH_DONE).
An earlier attempt to fix this (commit 3b8981b6, later reverted) missed
one special case. When the inner side is empty (the "empty inner
optimization), the build barrier would only make it to
PHJ_BUILD_HASHING_INNER phase before workers attempted to detach from
the hashtable. In that case, fast-forward the build barrier to
PHJ_BUILD_RUNNING before proceeding, so that our later assertions hold
and we can still negotiate who is cleaning up.
Revealed by build farm failures, where BarrierAttach() failed a sanity
check assertion, because the memory had been clobbered by dsa_free().
In non-assert builds, the result could be a segmentation fault.

@extschema:name@ extends the existing @extschema@ feature so that
we can also insert the schema name of some required extension,
thus making cross-extension references robust even if they are in
different schemas.
However, this has the same hazard as @extschema@: if the schema
name is embedded literally in an installed object, rather than being
looked up once during extension script execution, then it's no longer
safe to relocate the other extension to another schema. To deal with
that without restricting things unnecessarily, add a "no_relocate"
option to extension control files. This allows an extension to
specify that it cannot handle relocation of some of its required
extensions, even if in themselves those extensions are relocatable.
We detect "no_relocate" requests of dependent extensions during
ALTER EXTENSION SET SCHEMA.

When determining whether an index update may be skipped by using HOT, we
can ignore attributes indexed by block summarizing indexes without
references to individual tuples that need to be cleaned up.
A new type TU_UpdateIndexes provides a signal to the executor to
determine which indexes to update - no indexes, all indexes, or only the
summarizing indexes.
This also removes rd_indexattr list, and replaces it with rd_attrsvalid
flag. The list was not used anywhere, and a simple flag is sufficient.
This was originally committed as 5753d4ee32, but then got reverted by
e3fcca0d0d because of correctness issues.

When calculating distance in brin_minmax_multi_distance_inet(), the
netmask was applied incorrectly. This results in (seemingly) incorrect
ordering of values, triggering an assert.
For builds without asserts this is mostly harmless - we may merge other
ranges, possibly resulting in slightly less efficient index. But it's
still correct and the greedy algorithm doesn't guarantee optimality
anyway.

The Memoize executor node stores the cache key values along with the
tuple(s) which were found in the outer node which match each key value,
however, when the planner tried to estimate how many entries could be
stored in the cache, it didn't take into account that the cache key must
also be stored. In many cases, this won't make a large difference as the
key is likely small in comparison to the tuple(s) being stored, however,
it's not impossible to craft cases where the key could take more memory
than the tuple(s) stored for it.
Here we adjust the planner so it takes into account the estimated amount
of memory to store the cache key. Effectively, this change will reduce
the estimated cache hit ratio when it's thought that not all items will
fit in the cache, thus Memoize will become more expensive in such cases.
The executor already takes into account the memory consumed by the cache
key, so here we only need to adjust the planner.

When probing the Memoize cache to check if the current cache key values
exist in the cache, we perform an evaluation of the expressions making up
the cache key before probing the hash table for those values. This
operation could leak memory as it is possible that the cache key is an
expression which requires allocation of memory, as was the case in bug
17844.
Here we fix this by correctly switching to the per tuple context before
evaluating the cache expressions so that the memory is freed next time the
per tuple context is reset.

Instead of trying to optimize this by skipping creation of the
links for tables we don't plan to dump, just create them all in
bulk with a single scan over the pg_inherits data. The previous
approach was more or less O(N^2) in the number of pg_inherits
entries, not to mention being way too complicated.
Also, don't create useless TableAttachInfo objects.
It's silly to create a TableAttachInfo object that we're not
going to dump, when we know perfectly well at creation time
that it won't be dumped.

Hash partitioning on an enum is problematic because the hash codes are
derived from the OIDs assigned to the enum values, which will almost
certainly be different after a dump-and-reload than they were before.
This means that some rows probably end up in different partitions than
before, causing restore to fail because of partition constraint
violations. (pg_upgrade dodges this problem by using hacks to force
the enum values to keep the same OIDs, but that's not possible nor
desirable for pg_dump.)
Users can work around that by specifying --load-via-partition-root,
but since that's a dump-time not restore-time decision, one might
find out the need for it far too late. Instead, teach pg_dump to
apply that option automatically when dealing with a partitioned
table that has hash-on-enum partitioning.
Also deal with a pre-existing issue for --load-via-partition-root
mode: in a parallel restore, we try to TRUNCATE target tables just
before loading them, in order to enable some backend optimizations.
This is bad when using --load-via-partition-root because (a) we're
likely to suffer deadlocks from restore jobs trying to restore rows
into other partitions than they came from, and (b) if we miss getting
a deadlock we might still lose data due to a TRUNCATE removing rows
from some already-completed restore job.
The fix for this is conceptually simple: just don't TRUNCATE if we're
dealing with a --load-via-partition-root case. The tricky bit is for
pg_restore to identify those cases. In dumps using COPY commands we
can inspect each COPY command to see if it targets the nominal target
table or some ancestor. However, in dumps using INSERT commands it's
pretty impractical to examine the INSERTs in advance. To provide a
solution for that going forward, modify pg_dump to mark TABLE DATA
items that are using --load-via-partition-root with a comment.
(This change also responds to a complaint from Robert Haas that
the dump output for --load-via-partition-root is pretty confusing.)
pg_restore checks for the special comment as well as checking the
COPY command if present. This will fail to identify the combination
of --load-via-partition-root and --inserts in pre-existing dump files,
but that should be a pretty rare case in the field. If it does
happen you will probably get a deadlock failure that you can work
around by not using parallel restore, which is the same as before
this bug fix.
Having done this, there seems no remaining reason for the alarmism
in the pg_dump man page about combining --load-via-partition-root
with parallel restore, so remove that warning.
Patch by me; thanks to Julien Rouhaud for review. Back-patch to
v11 where hash partitioning was introduced.

Since commit 7627b91cd5d, libpq has used FD_CLOEXEC so that sockets
wouldn't be leaked to subprograms. With enough bad luck, a
multi-threaded program might fork in between the socket() and fcntl()
calls. We can close that tiny gap by using SOCK_CLOEXEC instead of a
separate call. While here, we might as well do the same for
SOCK_NONBLOCK, to save another syscall.
These flags are expected to appear in the next revision of the POSIX
standard, specifically to address this problem. Our Unixoid targets
except macOS and AIX have had them for a long time, and macOS would
hopefully use guarded availability to roll them out, so it seems enough
to use a simple ifdef test for availability until we hear otherwise.
Windows doesn't have them, but has non-inheritable sockets by default.

Unfortunately it turns out that the logfile-only option added in b9f8d1cbad7
is only available in openldap starting in 2.6.
Luckily the option to control the log level (loglevel/-s) have been around for
much longer. As it turns out loglevel/-s only control what goes into syslog,
not what ends up in the file specified with 'logfile' and stderr.
While we currently are specifying 'logfile', nothing ends up in it, as the
option only controls debug messages, and we didn't set a debug level. The
debug level can only be configured on the commandline and also prevents
forking. That'd require larger changes, so this commit doesn't tackle that
issue.
Specify the syslog level when starting slapd using -s, as that allows to
prevent all syslog messages if one uses '0' instead of 'none', while loglevel
doesn't prevent the first message.

DecodeDateTime and DecodeTimeOnly had support for date input in the
style "Y2023M03D16", which the comments claimed to be an "ISO" format.
However, so far as I can find there is no such format in ISO 8601;
they write units before numbers in intervals, but not in datetimes.
Furthermore, the lesser-known ISO 8601-2 spec actually defines an
incompatible format "2023Y03M16D". None of our documentation mentions
such a format either. So let's just drop it.
That leaves us with only two cases for a prefix unit specifier in
datetimes: Julian dates written as Jnnnn, and the "T" separator
defined by ISO 8601. Add checks to catch misuse of these specifiers,
that is consecutive specifiers or a dangling specifier at the end of
the string. We do not however disallow a specifier that is separated
from the field that it disambiguates (by noise words or unrelated
fields). That being the case, remove some overly-aggressive error
checks from the ISOTIME cases.

In the .pc (pkg-config) files generated by the make and meson builds,
the Requires.private entries use different delimiters. The make build
uses spaces, the meson build uses commas. The pkg-config documentation
says that it should be comma-separated, but apparently about half the
.pc in the wild use just spaces. The pkg-config source code
acknowledges that both commas and spaces work.
This changes the make build to use commas, for consistency.

This structure included only PgStat_FunctionCounts, and removing it
facilitates some upcoming refactoring for pgstatfuncs.c to use more
macros rather that mostly-duplicated functions.

A failure in parsing the interval value defined in the \watch command
was silently switched to 1s of interval between two queries, which can
be confusing. This commit improves the error handling, and a couple of
tests are added to check after:
- An incorrect value.
- An out-of-range value.
- A negative value.
A value of zero is able to work now, meaning that there is no interval
of time between two queries in a \watch loop. No backpatch is done, as
it could break existing applications.

This adds the ability to pretty-print XML documents ... according to
libxml's somewhat idiosyncratic notions of what's pretty, anyway.
One notable divergence from a strict reading of the spec is that
libxml is willing to collapse empty nodes "<node></node>" to just
"<node/>", whereas SQL and the underlying XML spec say that this
option should only result in whitespace tweaks. Nonetheless,
it seems close enough to justify using the SQL-standard syntax.

The hook can be installed by a shared_preload library.
A similar mechanism could be used for radius paswords, for example, and
the type name auth_password_hook_typ has been shosen with that in mind.

preprocess_targetlist thought PHVs couldn't appear here.
It was mistaken, as per report from Önder Kalacı.
Surveying other pull_var_clause calls, I noted no similar errors,
but I did notice that qual_is_pushdown_safe's assertion about
!contain_window_function was pointless, because the following
pull_var_clause call would complain about them anyway. In HEAD
only, remove the redundant Assert and improve the commentary.
