Some locales use a comma as decimal separator (like Czech or French),
and psql's 001_basic.pl for \timing was not able to handle that
properly. This fixes the matching regexes to be able to handle both
comma and dot as possible decimal separators, as per a suggestion from
Andrew Dunstan.
psql tests were the only place with such a portability issue
(check-world passed here with a forced LANG/LANGUAGE). These tests are
new as of c0280bc, so there is no need for a backpatch.

38bfae3 has moved the contents written to files by pg_upgrade under a
new directory called pg_upgrade_output.d/ located in the new cluster's
data folder, and it used a simple structure made of two subdirectories
leading to a fixed structure: log/ and dump/. This design has made
weaker pg_upgrade on repeated calls, as we could get failures when
creating one or more of those directories, while potentially losing the
logs of a previous run (logs are retained automatically on failure, and
cleaned up on success unless --retain is specified). So a user would
need to clean up pg_upgrade_output.d/ as an extra step for any repeated
calls of pg_upgrade. The most common scenario here is --check followed
by the actual upgrade, but one could see a failure when specifying an
incorrect input argument value. Removing entirely the logs would have
the disadvantage of removing all the past information, even if --retain
was specified at some past step.
This result is annoying for a lot of users and automated upgrade flows.
So, rather than requiring a manual removal of pg_upgrade_output.d/, this
redesigns the set of output directories in a more dynamic way, based on
a suggestion from Tom Lane and Daniel Gustafsson. pg_upgrade_output.d/
is still the base path, but a second directory level is added, mostly
named after an ISO-8601-formatted timestamp (in short human-readable,
with milliseconds appended to the name to avoid any conflicts). The
logs and dumps are saved within the same subdirectories as previously,
as of log/ and dump/, but these are located inside the subdirectory
named after the timestamp.
The logs of a given run are removed only after a successful run if
--retain is not used, and pg_upgrade_output.d/ is kept if there are any
logs from a previous run. Note that previously, pg_upgrade would have
kept the logs even after a successful --check but that was inconsistent
compared to the case without --check when using --retain. The code in
charge of the removal of the output directories is now refactored into a
single routine.
Two TAP tests are added with some --check commands (one failure case and
one success case), to look after the issue fixed here. Note that the
tests had to be tweaked a bit to fit with the new directory structure so
as it can find any logs generated on failure. This is still going to
require a change in the buildfarm client for the case where pg_upgrade
is tested without the TAP test, though, but I'll tackle that with a
separate patch where needed.

Bug #17512 highlighted that a suitably broken data type could cause the
backend to crash if either the hash function or equality function were in
someway non-deterministic based on their input values. Such a data type
could cause a crash of the backend due to some code which assumes that
we'll always find a hash table entry corresponding to an item in the
Memoize LRU list.
Here we remove the assumption that we'll always find the entry
corresponding to the given LRU list item and add run-time checks to verify
we have found the given item in the cache.
This is not a fix for bug #17512, but it will turn the crash reported by
that bug report into an internal ERROR.

pg_stat_get_subscription scanned one more LogicalRepWorker array entry
than is really allocated. In the worst case this could lead to SIGSEGV,
if the LogicalRepCtx data structure is near the end of shared memory.
That seems quite unlikely though (thanks to the ordering of calls in
CreateSharedMemoryAndSemaphores) and we've heard no field reports of it.
A more likely misbehavior is one row of garbage data in the function's
result, but even that is not real likely because of the check that the
pid field matches some live backend.

psql --single-transaction is able to handle multiple -c and -f switches
in a single transaction since d5563d7d, but this had the surprising
behavior of forcing a transaction COMMIT even if psql failed with an
error in the client (for example incorrect path given to \copy), which
would generate an error, but still commit any changes that were already
applied in the backend. This commit makes the behavior more consistent,
by enforcing a transaction ROLLBACK if any commands fail, both
client-side and backend-side, so as no changes are applied if one error
happens in any of them.
Some tests are added on HEAD to provide some coverage about all that.
Backend-side errors are unreliable as IPC::Run can complain on SIGPIPE
if psql quits before reading a query result, but that should work
properly in the case where any errors come from psql itself, which is
what the original report is about.

The hard-wired PageOutput arguments in usage() and sibling functions
have been a perennial maintenance gotcha, and there's no reason to
think we'll ever get any better about that. Let's get rid of those
magic constants by constructing the output in a buffer where we can
count the newlines before calling PageOutput. (Perhaps this is
microscopically slower; but none of these functions are performance
critical, and anyway we might well be buying back all the cost by
avoiding having to pass most of the data through snprintf.c. I could
not detect any speed difference in a desultory check.) This also
gets rid of the need to assume that platform-specific variations in
the output are insignificant.
While at it, make the code shorter and more abstract by inventing
helper macros HELP0() and HELPN() to encapsulate the specific
output actions being invoked.

TAP tests are run from their own directory in the source tree, and in a
VPATH build the execution of the pg_upgrade command was leaving behind a
file in the source tree, that should be left untouched. In order to
avoid this issue, the test moves to PostgreSQL::Test::Utils::tmp_check,
so as any files generated by pg_upgrade do not impact the source tree,
but the build tree. This has as nice side-effect to make unnessary the
presence of such files in pg_upgrade's .gitignore and Makefile. This
strategy is similar to psql's test 010_tab_completion.pl, though the
reasons behind this choice are different.
In passing, fix one misleading test name that was added by 99f6f19.

Currently, we simply combine the column lists when publishing tables on
multiple publications and that can sometimes lead to unexpected behavior.
Say, if a column is published in any row-filtered publication, then the
values for that column are sent to the subscriber even for rows that don't
match the row filter, as long as the row matches the row filter for any
other publication, even if that other publication doesn't include the
column.
The main purpose of introducing a column list is to have statically
different shapes on publisher and subscriber or hide sensitive column
data. In both cases, it doesn't seem to make sense to combine column
lists.
So, we disallow the cases where the column list is different for the same
table when combining publications. It can be later extended to combine the
column lists for selective cases where required.

This reverts commit d9d076222f5b "VACUUM: ignore indexing operations
with CONCURRENTLY".
These changes caused indexes created with the CONCURRENTLY option to
miss heap tuples that were HOT-updated and HOT-pruned during the index
creation. Before these changes, HOT pruning would have been prevented
by the Xmin of the transaction creating the index, but because this
change was precisely to allow the Xmin to move forward ignoring that
backend, now other backends scanning the table can prune them. This is
not a problem for VACUUM (which requires a lock that conflicts with a
CREATE INDEX CONCURRENTLY operation), but HOT-prune can definitely
occur. In other words, Xmin advancement was sped up, but at the cost of
corrupting the resulting index.
Regrettably, this means that the new feature in PG14 that RIC/CIC on
very large tables no longer force VACUUM to retain very old tuples goes
away. We might try to implement it again in a later release, but for
now the risk of indexes missing tuples is too high and there's no easy
fix.
Backpatch to 14, where this change appeared.

We hadn't noticed this because (a) few people feed invalid
timezone abbreviation files to the server, and (b) in typical
scenarios guc.c would throw ereport(ERROR) and then transaction
abort handling would silently clean up the leaked file reference.
However, it was possible to observe file leakage warnings if one
breaks an already-active abbreviation file, because guc.c does
not throw ERROR when loading supposedly-validated settings during
session start or SIGHUP processing.

Commit 1a36bc9db (SQL/JSON query functions) introduced STRING as a
type_func_name_keyword, thereby breaking applications that use
"string" as a table name, column name, function parameter name, etc.
That seems like a pretty bad thing, not least because the SQL spec
says that STRING is an unreserved keyword.
This is easy enough to fix so far as the core grammar is concerned.
However, doing so causes some ECPG test cases to fail, specifically
those that use "string" as a typedef name. It turns out this is
because portions of the ECPG grammar allow type_func_name_keywords
but not unreserved_keywords as typedef names. That's pretty horrid,
and it's mildly astonishing that we've not heard complaints about it
before. We can fix two of those uses trivially, but the ones in the
var_type production are less easy. As a stopgap, hard-code STRING as
an allowed alternative in var_type.

This reverts commit 06f5295 as per issues with this approach, both in
terms of efficiency impact and stability. First, contrary to the
single-item cache for transaction IDs in transam.c, the cache may finish
by not be hit for a long time, and without an invalidation mechanism to
clear it, it would cause inconsistent results on wraparound for
example. Second, the use of SubTransGetTopmostTransaction() for the
caching has a limited impact on performance. SubTransGetParent() could
have more impact, though the benchmarking of the single-item approach
still needs to be proved, particularly under the conditions where SLRU
lookups are stressed in parallel with overflowed snapshots (aka more
than 64 subxids generated, for example).

9d9c02ccd added code to allow the executor to take shortcuts when quals
on monotonic window functions guaranteed that once the qual became false
it could never become true again. When possible, baserestrictinfo quals
are converted to become these quals, which we call run conditions.
Unfortunately, in 9d9c02ccd, I forgot to update
remove_unused_subquery_outputs to teach it about these run conditions.
This could cause a WindowFunc column which was unused in the target list
but referenced by an upper-level WHERE clause to be removed from the
subquery when the qual in the WHERE clause was converted into a window run
condition. Because of this, the entire WindowClause would be removed from
the query resulting in additional rows making it into the resultset when
they should have been filtered out by the WHERE clause.
Here we fix this by recording which target list items in the subquery have
run conditions. That gets passed along to remove_unused_subquery_outputs
to tell it not to remove these items from the target list.

Commits a59c79564 et al. tried to sync libpq's SSL key file
permissions checks with what we've used for years in the backend.
We did not intend to create any new failure cases, but it turns out
we did: restricting the key file's ownership breaks cases where the
client is allowed to read a key file despite not having the identical
UID. In particular a client running as root used to be able to read
someone else's key file; and having seen that I suspect that there are
other, less-dubious use cases that this restriction breaks on some
platforms.
We don't really need an ownership check, since if we can read the key
file despite its having restricted permissions, it must have the right
ownership --- under normal conditions anyway, and the point of this
patch is that any additional corner cases where that works should be
deemed allowable, as they have been historically. Hence, just drop
the ownership check, and rearrange the permissions check to get rid
of its faulty assumption that geteuid() can't be zero. (Note that the
comparable backend-side code doesn't have to cater for geteuid() == 0,
since the server rejects that very early on.)
This does have the end result that the permissions safety check used
for a root user's private key file is weaker than that used for
anyone else's. While odd, root really ought to know what she's doing
with file permissions, so I think this is acceptable.

repeat() checked for integer overflow during its calculation of the
required output space, but it just passed the resulting integer to
palloc(). This meant that result sizes between 1GB and 2GB led to
ERRCODE_INTERNAL_ERROR, "invalid memory alloc request size" rather
than ERRCODE_PROGRAM_LIMIT_EXCEEDED, "requested length too large".
That seems like a bit of a wart, so add an explicit AllocSizeIsValid
check to make these error cases uniform.
Do likewise in the sibling functions lpad() etc. While we're here,
also modernize their overflow checks to use pg_mul_s32_overflow() etc
instead of expensive divisions.
Per complaint from Japin Li. This is basically cosmetic, so I don't
feel a need to back-patch.

Mistake in 5891c7a8ed8, likely made when switching the default value from none
to fetch during development.

Upper-case MATCH so that it is clearer that it is a keyword in this
context.

"\r" (for progress output) must not be inside a translatable string
(gettext gets upset).
In passing, move the minimum supported version number to a separate
argument, so that we don't have to retranslate this string every year
now.

This was apparently missed in the original commit.
