ff34ae368b Support absolute bindir/libdir in regression tests with meson
Passing an absolute bindir/libdir will install the binaries and
libraries to <build>/tmp_install/<bindir> and
<build>/tmp_install/<libdir> respectively.

This path is correctly passed to the regression test suite via
configure/make, but not via meson, yet. This is because the "/"
operator in the following expression throws away the whole left side
when the right side is an absolute path:

    test_install_location / get_option('libdir')

This was already correctly handled for dir_prefix, which is likely
absolute as well. This patch handles both bindir and libdir in the
same way - prefixing absolute paths with the tmp_install path
correctly.

a00fae9d43 Fallback to uuid for ossp-uuid with meson
The upstream name for the ossp-uuid package / pkg-config file is
"uuid". Many distributions change this to be "ossp-uuid" to not
conflict with e2fsprogs.

This lookup fails on distributions which don't change this name, for
example NixOS / nixpkgs. Both "ossp-uuid" and "uuid" are also checked
in configure.ac.

0dcaea5690 Introduce num_os_semaphores GUC.
The documentation for System V IPC parameters provides complicated
formulas to determine the appropriate values for SEMMNI and SEMMNS.
Furthermore, these formulas have often been wrong because folks
forget to update them (e.g., when adding a new auxiliary process).

This commit introduces a new runtime-computed GUC named
num_os_semaphores that reports the number of semaphores needed for
the configured number of allowed connections, worker processes,
etc.  This new GUC allows us to simplify the formulas in the
documentation, and it should help prevent future inaccuracies.
Like the other runtime-computed GUCs, users can view it with
"postgres -C" before starting the server, which is useful for
preconfiguring the necessary operating system resources.

8a53539bd6 Wait for WAL summarization to catch up before creating .partial file.
When a standby is promoted, CleanupAfterArchiveRecovery() may decide
to rename the final WAL file from the old timeline by adding ".partial"
to the name. If WAL summarization is enabled and this file is renamed
before its partial contents are summarized, WAL summarization breaks:
the summarizer gets stuck at that point in the WAL stream and just
errors out.

To fix that, first make the startup process wait for WAL summarization
to catch up before renaming the file. Generally, this should be quick,
and if it's not, the user can shut off summarize_wal and try again.
To make this fix work, also teach the WAL summarizer that after a
promotion has occurred, no more WAL can appear on the previous
timeline: previously, the WAL summarizer wouldn't switch to the new
timeline until we actually started writing WAL there, but that meant
that when the startup process was waiting for the WAL summarizer, it
was waiting for an action that the summarizer wasn't yet prepared to
take.

In the process of fixing these bugs, I realized that the logic to wait
for WAL summarization to catch up was spread out in a way that made
it difficult to reuse properly, so this code refactors things to make
it easier.

Finally, add a test case that would have caught this bug and the
previously-fixed bug that WAL summarization sometimes needs to back up
when the timeline changes.

454aab4b73 postgres_fdw: Fix bug in connection status check.
The buildfarm member "hake" reported a failure in the regression test
added by commit 857df3cef7, where postgres_fdw_get_connections(true)
returned unexpected results.

The function postgres_fdw_get_connections(true) checks
if a connection is closed by using POLLRDHUP in the requested events
and calling poll(). Previously, the function only considered
POLLRDHUP or 0 as valid returned events. However, poll() can also
return POLLHUP, POLLERR, and/or POLLNVAL. So if any of these events
were returned, postgres_fdw_get_connections(true) would report
incorrect results. postgres_fdw_get_connections(true) failed to
account for these return events.

This commit updates postgres_fdw_get_connections(true) to correctly
report a closed connection when poll() returns not only POLLRDHUP
but also POLLHUP, POLLERR, or POLLNVAL.

4b56bb4ab4 pg_upgrade: Move live_check variable to user_opts.
At the moment, pg_upgrade stores whether it is doing a "live check"
(i.e., the user specified --check and the old server is still
running) in a local variable scoped to main().  This live_check
variable is passed to several functions.  To further complicate
matters, a few call sites provide a hard-coded "false" as the
live_check argument.  Specifically, this is done when calling these
functions for the new cluster, for which any live-check-only paths
won't apply.

This commit moves the live_check variable to the global user_opts
variable, which stores information about the options the user
specified on the command line.  This allows us to remove the
live_check parameter from several functions.  For the functions
with callers that provide a hard-coded "false" as the live_check
argument (e.g., get_control_data()), we verify the given cluster is
the old cluster before taking any live-check-only paths.

This small refactoring effort helps simplify some proposed changes
that would parallelize many of pg_upgrade's once-in-each-database
tasks using libpq's asynchronous APIs.  By removing the live_check
parameter, we can more easily convert the functions to callbacks
for the new parallel system.

cf8a489836 Allow WAL summarization to back up when timeline changes.
The old code believed that it was not possible to switch timelines
without first replaying all of the WAL from the old timeline, but
that turns out to be false, as demonstrated by an example from Fujii
Masao. As a result, it assumed that summarization would always
continue from the LSN where summarization previously ended. But in
fact, when a timeline switch occurs without replaying all the WAL
from the previous timeline, we can need to back up to an earlier
LSN. Adjust accordingly.

c297a47c5f postgres_fdw: Add "used_in_xact" column to postgres_fdw_get_connections().
This commit extends the postgres_fdw_get_connections() function to
include a new used_in_xact column, indicating whether each connection
is used in the current transaction.

This addition is particularly useful for the upcoming feature that
will check if connections are closed. By using those information,
users can verify if postgres_fdw connections used in a transaction
remain open. If any connection is closed, the transaction cannot
be committed successfully. In this case users can roll back it
immediately without waiting for transaction end.

The SQL API for postgres_fdw_get_connections() is updated by
this commit and may change in the future. To handle compatibility
with older SQL declarations, an API versioning system is introduced,
allowing the function to behave differently based on the API version.

which was fixed in the previous commit.

This adds an IS_INJECTION_POINT_ATTACHED() macro, to allow writing
injected test code alongside the normal source code. In principle, the
new test could've been implemented by an extra test module with a
callback that sets the FrontendProtocol global variable, but I think
it's more clear to have the test code right where the injection point

32d3ed8165 Add path column to pg_backend_memory_contexts view
"path" provides a reliable method of determining the parent/child
relationships between memory contexts.  Previously this could be done in
a non-reliable way by writing a recursive query and joining the "parent"
and "name" columns.  This wasn't reliable as the names were not unique,
which could result in joining to the wrong parent.

To make this reliable, "path" stores an array of numerical identifiers
starting with the identifier for TopLevelMemoryContext.  It contains an
element for each intermediate parent between that and the current context.

Incompatibility: Here we also adjust the "level" column to make it
1-based rather than 0-based.  A 1-based level provides a convenient way
to access elements in the "path" array. e.g. path[level] gives the
identifier for the current context.

Identifiers are not stable across multiple evaluations of the view.  In
an attempt to make these more stable for ad-hoc queries, the identifiers
are assigned breadth-first.  Contexts closer to TopLevelMemoryContext
are less likely to change between queries and during queries.

64c39bd504 ci: Pin MacPorts version to 2.9.3.
Commit d01ce180 invented a new way to find the latest MacPorts version.
By bad luck, a new beta release has just been published, and it seems
to lack some packages we need.  Go back to searching for this specific
version for now.  We still search with a pattern so that we can find the
package for the running version of macOS, but for now we always look for
2.9.3.  The code to do that had been anticipated already in a commented
out line, I just didn't expect to have to use it so soon...

Also include the whole MacPorts installation script in the cache key, so
that changes to the script cause a fresh installation.  This should make
it a bit easier to reason about the effect of changes on cached state in
github accounts using CI, when we make adjustments.

Back-patch to 15, like d01ce180.

d01ce180d9 ci: Upgrade macOS version from 13 to 14.
1.  Previously we were using ghcr.io/cirruslabs/macos-XXX-base:latest
images, but Cirrus has started ignoring that and using a particular
image, currently ghcr.io/cirruslabs/macos-runner:sonoma, for github
accounts using free CI resources (as opposed to dedicated runner
machines, as cfbot uses).  Let's just ask for that image anyway, to stay
in sync.

2.  Instead of hard-coding a MacPorts installation URL, deduce it from
the running macOS version and the available releases.  This removes the
need to keep the ci_macports_packages.sh in sync with .cirrus.task.yml,
and to advance the MacPorts version from time to time.

3.  Change the cache key we use to cache the whole macports installation
across builds to include the OS major version, to trigger a fresh
installation when appropriate.

Back-patch to 15 where CI began.

364509a2e7 pg_upgrade: Retrieve subscription count more efficiently.
Presently, pg_upgrade obtains the number of subscriptions in the
to-be-upgraded cluster by first querying pg_subscription in every
database for the number of subscriptions in only that database.
Then, in count_old_cluster_subscriptions(), it adds all the values
collected in the first step.  This is expensive, especially when
there are many databases.

Fortunately, there is a better way to retrieve the subscription
count.  Since pg_subscription is a shared catalog, we only need to
connect to a single database and query it once.  This commit
modifies pg_upgrade to use that approach, which also allows us to
trim several lines of code.  In passing, move the call to
get_db_subscription_count(), which has been renamed to
get_subscription_count(), from get_db_rel_and_slot_infos() to the
dedicated >= v17 section in check_and_dump_old_cluster().

We may be able to make similar improvements to
get_old_cluster_logical_slot_infos(), but that is left as a future
exercise.

Reset relhassubclass upon attaching table as a partition
We don't allow inheritance parents as partitions, and have checks to
prevent this; but if a table _was_ in the past an inheritance parents
and all their children are removed, the pg_class.relhassubclass flag
may remain set, which confuses the partition pruning code (most
obviously, it results in an assertion failure; in production builds it
may be worse.)

Fix by resetting relhassubclass on attach.

Backpatch to all supported versions.

f6bef362ca Refactor tidstore.c iterator buffering.
Previously, TidStoreIterateNext() would expand the set of offsets for
each block into an internal buffer that it overwrote each time.  In
order to be able to collect the offsets for multiple blocks before
working with them, change the contract.  Now, the offsets are obtained
by a separate call to TidStoreGetBlockOffsets(), which can be called at
a later time.  TidStoreIteratorResult objects are safe to copy and store
in a queue.

1462aad2e4 Allow altering of two_phase option of a SUBSCRIPTION.
The two_phase option is controlled by both the publisher (as a slot
option) and the subscriber (as a subscription option), so the slot option
must also be modified.

Changing the 'two_phase' option for a subscription from 'true' to 'false'
is permitted only when there are no pending prepared transactions
corresponding to that subscription. Otherwise, the changes of already
prepared transactions can be replicated again along with their corresponding
commit leading to duplicate data or errors.

To avoid data loss, the 'two_phase' option for a subscription can only be
changed from 'false' to 'true' once the initial data synchronization is
completed. Therefore this is performed later by the logical replication worker.

774d47b6c0 Move all extern declarations for GUC variables to header files
Add extern declarations in appropriate header files for global
variables related to GUC.  In many cases, this was handled quite
inconsistently before, with some GUC variables declared in a header
file and some only pulled in via ad-hoc extern declarations in various
.c files.

Also add PGDLLIMPORT qualifications to those variables.  These were
previously missing because src/tools/mark_pgdllimport.pl has only been
used with header files.

This also fixes -Wmissing-variable-declarations warnings for GUC
variables (not yet part of the standard warning options).

991f8cf8ab Detect integer overflow in array_set_slice().
When provided an empty initial array, array_set_slice() fails to
check for overflow when computing the new array's dimensions.
While such overflows are ordinarily caught by ArrayGetNItems(),
commands with the following form are accepted:

	INSERT INTO t (i[-2147483648:2147483647]) VALUES ('{}');

To fix, perform the hazardous computations using overflow-detecting
arithmetic routines.  As with commit 18b585155a, the added test
cases generate errors that include a platform-dependent value, so
we again use psql's VERBOSITY parameter to suppress printing the
message text.
