We stopped defining IOV_MAX on non-Windows systems in 75357ab94, on
the assumption that every non-Windows system defines it in <limits.h>
as required by X/Open. GNU Hurd, however, doesn't follow that
standard either. Put back the old logic to assume 16 if it's
not defined.

The existing code assumed that O_RDONLY is defined as 0, but this is
not required by POSIX and is not true on GNU Hurd. We can avoid
the assumption by relying on O_ACCMODE to mask the fcntl() result.

Querying the NUMA status can be quite time consuming, especially with
large shared buffers. 8cc139bec34a called numa_move_pages() once, for
all buffers, and we had to wait for the syscall to complete.
But with the chunking, introduced by 7fe2f67c7c to work around a kernel
bug, we can do CHECK_FOR_INTERRUPTS() after each chunk, allowing users
to abort the execution.

When querying NUMA status of pages in shared memory, we need to touch
the memory first to get valid results. This may trigger valgrind
reports, because some of the memory (e.g. unpinned buffers) may be
marked as noaccess.
Solved by adding a valgrind suppresion. An alternative would be to
adjust the access/noaccess status before touching the memory, but that
seems far too invasive. It would require all those places to have
detailed knowledge of what the shared memory stores.
The pg_numa_touch_mem_if_required() macro is replaced with a function.
Macros are invisible to suppressions, so it'd have to suppress reports
for the caller - e.g. pg_get_shmem_allocations_numa(). So we'd suppress
reports for the whole function, and that seems to heavy-handed. It might
easily hide other valid issues.

There's a kernel bug in do_pages_stat(), affecting systems combining
64-bit kernel and 32-bit user space. The function splits the request
into chunks of 16 pointers, but forgets the pointers are 32-bit when
advancing to the next chunk. Some of the pointers get skipped, and
memory after the array is interpreted as pointers. The result is that
the produced status of memory pages is mostly bogus.
Systems combining 64-bit and 32-bit environments like this might seem
rare, but that's not the case - all 32-bit Debian packages are built in
a 32-bit chroot on a system with a 64-bit kernel.
This is a long-standing kernel bug (since 2010), affecting pretty much
all kernels, so it'll take time until all systems get a fixed kernel.
Luckily, we can work around the issue by chunking the requests the same
way do_pages_stat() does, at least on affected systems. We don't know
what kernel a 32-bit build will run on, so all 32-bit builds use chunks
of 16 elements (the largest chunk before hitting the issue).
64-bit builds are not affected by this issue, and so could work without
the chunking. But chunking has other advantages, so we apply chunking
even for 64-bit builds, with chunks of 1024 elements.

The contrib module xml2/ has always been fuzzy with the cleanup of the
memory allocated by the calls internal to libxml2, even if there are
APIs in place giving a lot of control over the error behavior, all
located in the backend's xml.c.
The code paths fixed in the commit address multiple defects, while
sanitizing the code:
- In xpath.c, several allocations are done by libxml2 for
xpath_workspace, whose memory cleanup could go out of sight as it relied
on a single TRY/CATCH block done in pgxml_xpath(). workspace->res is
allocated by libxml2, and may finish by not being freed at all upon a
failure outside of a TRY area. This code is refactored so as the
TRY/CATCH block of pgxml_xpath() is moved one level higher to its
callers, which are responsible for cleaning up the contents of a
workspace on failure. cleanup_workspace() now requires a volatile
workspace, forcing as a rule that a TRY/CATCH block should be used.
- Several calls, like xmlStrdup(), xmlXPathNewContext(),
xmlXPathCtxtCompile(), etc. can return NULL on failures (for most of
them allocation failures. These forgot to check for failures, or missed
that pg_xml_error_occurred() should be called, to check if an error is
already on the stack.
- Some memory allocated by libxml2 calls was freed in an incorrect way,
"resstr" in xslt_process() being one example.
The class of errors fixed here are for problems that are unlikely going
to happen in practice, so no backpatch is done. The changes have
finished by being rather invasive, so it is perhaps not a bad thing to
be conservative and to keep these changes only on HEAD anyway.

This commit fixes some defects in the backend's xml.c, found upon
inspection of the internals of libxml2:
- xmlEncodeSpecialChars() can fail on malloc(), returning NULL back to
the caller. xmltext() assumed that this could never happen. Like other
code paths, a TRY/CATCH block is added there, covering also the fact
that cstring_to_text_with_len() could fail a memory allocation, where
the backend would miss to free the buffer allocated by
xmlEncodeSpecialChars().
- Some libxml2 routines called in xmlelement() can return NULL, like
xmlAddChildList() or xmlTextWriterStartElement(). Dedicated errors are
added for them.
- xml_xmlnodetoxmltype() missed that xmlXPathCastNodeToString() can fail
on an allocation failure. In this case, the call can just be moved to
the existing TRY/CATCH block.
All these code paths would cause the server to crash. As this is
unlikely a problem in practice, no backpatch is done. Jim and I have
caught these defects, not sure who has scored the most. The contrib
module xml2/ has similar defects, which will be addressed in a separate
change.

The current code in resolve_column_ref (dating to commits 01f7d2990
and fe24d7816) believes that not finding a RECFIELD datum is a
can't-happen case, in consequence of which I didn't spend a whole lot
of time considering what to do if it did happen. But it turns out
that it *can* happen if the would-be field name is a fully-reserved
PL/pgSQL keyword. Change the error message to describe that
situation, and add a test case demonstrating it.
This might need further refinement if anyone can find other ways to
trigger a failure here; but without an example it's not clear what
other error to throw.

In the wake of commit a16ef313f, we need to deal with more cases
involving PlaceHolderVars in NestLoopParams than we did before.
For one thing, a16ef313f was incorrect to suppose that we could
rely on the required-outer relids of the lefthand path to decide
placement of nestloop-parameter PHVs. As Richard Guo argued at
the time, we must look at the required-outer relids of the join
path itself.
For another, we have to apply replace_nestloop_params() to such
a PHV's expression, in case it contains references to values that
will be supplied from NestLoopParams of higher-level nestloops.
For another, we need to be more careful about the phnullingrels
of the PHV than we were being. identify_current_nestloop_params
only bothered to ensure that the phnullingrels didn't contain
"too many" relids, but now it has to be exact, because setrefs.c
will apply both NRM_SUBSET and NRM_SUPERSET checks in different
places. We can compute the correct relids by determining the
set of outer joins that should be able to null the PHV and then
subtracting whatever's been applied at or below this join.
Do the same for plain Vars, too. (This should make it possible
to use NRM_EQUAL to process nestloop params in setrefs.c, but
I won't risk making such a change in v18 now.)
Lastly, if a nestloop parameter PHV was pulled up out of a subquery
and it contains a subquery that was originally pushed down from this
query level, then that will still be represented as a SubLink, because
SS_process_sublinks won't recurse into outer PHVs, so it didn't get
transformed during expression preprocessing in the subquery. We can
substitute the version of the PHV's expression appearing in its
PlaceHolderInfo to ensure that that preprocessing has happened.
(Seems like this processing sequence could stand to be redesigned,
but again, late in v18 development is not the time for that.)
It's not very clear to me why the old have_dangerous_phv join-order
restriction prevented us from seeing the last three of these problems.
But given the lack of field complaints, it must have done so.

Sometimes a table's constraint may depend on a column of another
table, so that we have to update the constraint when changing the
referenced column's type. We need to have lock on the constraint's
table to do that. ATPostAlterTypeCleanup believed that this case
was only possible for FOREIGN KEY constraints, but it's wrong at
least for CHECK and EXCLUDE constraints; and in general, we'd
probably need exclusive lock to alter any sort of constraint.
So just remove the contype check and acquire lock for any other
table. This prevents a "you don't have lock" assertion failure,
though no ill effect is observed in production builds.
We'll error out later anyway because we don't presently support
physically altering column types within stored composite columns.
But the catalog-munging is basically all there, so we may as well
make that part work.

This commit renames the pg_recvlogical options --two-phase and
--failover to --enable-two-phase and --enable-failover, respectively.
The new names distinguish these enabling options from action options
like --start and --create-slot, while clearly indicating their purpose
to enable specific logical slot features.
The option --failover is new in PostgreSQL 18 (commit cf2655a9029), so
no compatibility break there. The option --two-phase has existed
since PostgreSQL 15 (commit cda03cfed6b), so for compatibility we keep
the old option name --two-phase around as deprecated.
Also note that pg_createsubscriber has acquired an --enable-two-phase

ca307d5cec90 made CheckPointReplicationSlots() unconditionally call
ReplicationSlotsComputeRequiredLSN(). It causes an assertion trap when
max_replication_slots equals 0. This commit makes
CheckPointReplicationSlots() call ReplicationSlotsComputeRequiredLSN() only
when at least one slot gets its last_saved_restart_lsn updated. That avoids
an assert trap and also saves some cycles when no one slot has
last_saved_restart_lsn updated.
Based on ideas from Dilip Kumar <[email protected]> and
Hayato Kuroda <[email protected]>.

binaryheap.c and stringinfo.c have been moved to src/common/ by
respectively 5af0263afd7b and 26aaf97b683d, and the README patched here
still mentioned these two files as available in src/backend/lib/.

Commit 7d6d2c4bbd7 dropped opcintype from the index AM strategy
translation API. But some error messages about failed lookups still
mentioned it, even though it was not used for the lookup. Fix by
removing ipcintype from the error messages as well.

8e03eb92e9a reverted the commit 39b66a91bd which allowed freezing
in the heap_insert() code path but forgot to remove the corresponding
check in heap_xlog_insert(). This code is extraneous but not harmful.
However, cleaning it up makes it very clear that, as of now, we do not
support any freezing of pages in the heap_insert() path.
