Don't fail on libpq-generated error reports in ecpg_raise_backend().
An error PGresult generated by libpq itself, such as a report of
connection loss, won't have broken-down error fields.
ecpg_raise_backend() blithely assumed that PG_DIAG_MESSAGE_PRIMARY
would always be present, and would end up passing a NULL string
pointer to snprintf when it isn't. That would typically crash
before

Fix psql's single transaction mode on client-side errors with -c/-f switches
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.

Automatically count the number of output lines in psql/help.c.
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.

Prohibit combining publications with different column lists.
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.

Revert changes to CONCURRENTLY that "sped up" Xmin advance
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.

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,

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.
Per report from Yogendra Suralkar. Like the previous patch,
back-patch to all supported branches.

Avoid ERRCODE_INTERNAL_ERROR in oracle_compat.c functions.
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

Do likewise in the sibling functions lpad() etc. While we're here,
also modernize their overflow checks to use pg_mul_s32_overflow() etc

On slow machines the modified test could end up switching the order in which
transactional stats are reported in one session and non-transactional stats in
another session. As stats handling of truncate is implemented as setting
live/dead rows 0, the order in which a truncate's stats changes are applied,
relative to normal stats updates, matters. The handling of stats for truncate

Show 'AS "?column?"' explicitly when it's important.
ruleutils.c was coded to suppress the AS label for a SELECT output
expression if the column name is "?column?", which is the parser's
fallback if it can't think of something better. This is fine, and
avoids ugly clutter, so long as (1) nothing further up in the parse
tree relies on that column name or (2) the same fallback would be
assigned when the rule or view definition is reloaded. Unfortunately
(2) is far from certain, both because ruleutils.c might print the
expression in a different form from how it was originally written
and because FigureColname's rules might change in future releases.
So we shouldn't rely on that.
Detecting exactly whether there is any outer-level use of a SELECT
column name would be rather expensive. This patch takes the simpler
approach of just passing down a flag indicating whether there *could*
be any outer use; for example, the output column names of a SubLink
are not referenceable, and we also do not care about the names exposed
by the right-hand side of a setop. This is sufficient to suppress
unwanted clutter in all but one case in the regression tests. That
seems like reasonable evidence that it won't be too much in users'
faces, while still fixing the cases we need to fix.

Avoid overflow hazard when clamping group counts to "long int".
Several places in the planner tried to clamp a double value to fit
in a "long" by doing
(long) Min(x, (double) LONG_MAX);
This is subtly incorrect, because it casts LONG_MAX to double and
potentially back again. If long is 64 bits then the double value
is inexact, and the platform might round it up to LONG_MAX+1
resulting in an overflow and an undesirably negative output.
While it's not hard to rewrite the expression into a safe form,
let's put it into a common function to reduce the risk of someone
doing it wrong in future.
In principle this is a bug fix, but since the problem could only
manifest with group count estimates exceeding 2^63, it seems unlikely
that anyone has actually hit this or will do so anytime soon. We're
fixing it mainly to satisfy fuzzer-type tools. That being the case,
a HEAD-only fix seems sufficient.

outer_path->parent->rows instead of outer_path->rows. This failed to
account for the fact that the outer_path might be parameterized by some
upper-level Nested Loop.
This problem could lead to Memoize plans appearing more favorable than
they might actually be. It could also lead to extended executor startup
times when work_mem values were large due to the planner setting overly
large MemoizePath->est_entries resulting in the Memoize hash table being
initially made much larger than might be required.
Fix this simply by passing outer_path->rows rather than
outer_path->parent->rows. Also, adjust the expected regression test
output for a plan change.

Fix slow animal timeouts in 032_relfilenode_reuse.pl.
Per BF animal chipmunk: CREATE DATABASE could apparently fail due to an
AV process being in the template database and not quitting fast enough
for the 5 second timeout in CountOtherDBBackends(). The test script had
autovacuum_naptime=1s to encourage more activity and opening of fds, but
that wasn't strictly necessary for this test. Take it out.
Per BF animal skink: there was a 300s timeout for all tests in the
script, but apparently that was not enough under valgrind. Let's use
the standard timeout $PostgreSQL::Test::Utils::timeout_default, but
restart it for each query we run.

Rename JsonIsPredicate.value_type, fix JSON backend/nodes/ infrastructure.
I started out with the intention to rename value_type to item_type to
avoid a collision with a typedef name that appears on some platforms.
Along the way, I noticed that the adjacent field "format" was not being
correctly handled by the backend/nodes/ infrastructure functions:
copyfuncs.c erroneously treated it as a scalar, while equalfuncs,
outfuncs, and readfuncs omitted handling it at all. This looks like
it might be cosmetic at the moment because the field is always NULL
after parse analysis; but that's likely a bug in itself, and the code's
certainly not very future-proof. Let's fix it while we can still do so
without forcing an initdb on beta testers.
Further study found a few other inconsistencies in the backend/nodes/
infrastructure for the recently-added JSON node types, so fix those too.
catversion bumped because of potential change in stored rules.

Add a new shmem_request_hook hook.
Currently, preloaded libraries are expected to request additional
shared memory and LWLocks in _PG_init(). However, it is not unusal
for such requests to depend on MaxBackends, which won't be
initialized at that time. Such requests could also depend on GUCs
that other modules might change. This introduces a new hook where
modules can safely use MaxBackends and GUCs to request additional
shared memory and LWLocks.
Furthermore, this change restricts requests for shared memory and
LWLocks to this hook. Previously, libraries could make requests
until the size of the main shared memory segment was calculated.
Unlike before, we no longer silently ignore requests received at
invalid times. Instead, we FATAL if someone tries to request
additional shared memory or LWLocks outside of the hook.

libpq: drop pending pipelined commands in pqDropConnection().
The original coding did this in pqDropServerData(), which seems
fairly backwards. Pending commands are more like already-queued
output data, which is dropped in pqDropConnection(). Moving the
operation means that we clear the command queue immediately upon
detecting connection drop, which improves the sanity of subsequent
behavior. In particular this eliminates duplicated error message
text as a consequence of code added in
b15f25446, which supposed
that a nonempty command queue must mean the prior operation is
still active.
There might be an argument for backpatching this to v14; but as with
b15f25446, I'm unsure about interactions with
618c16707. For now,
given the lack of complaints about v14's behavior, leave it alone.
