This function has been incorrectly marked as a set-returning function
with prorows (estimated number of rows) set to 1 since its creation in
7117685, that introduced non-exclusive backups. There is no need for
that as the function is designed to return only one tuple.
This commit fixes the catalog definition of pg_stop_backup_v2() so as it
is not marked as proretset anymore, with prorows set to 0. This
simplifies its internals by removing one tuplestore (used for one single
record anyway) and by removing all the checks related to a set-returning
function.
Issue found during my quest to simplify some of the logic used in
in-core system functions.

The checks currently done at the startup of pg_upgrade on PGHOST and
PGHOSTADDR to avoid any attempts to access to an external cluster fail
setting those parameters to Windows paths or even temporary paths
prefixed by an '@', as it only considers as a valid path strings
beginning with a slash.
As mentioned by Andres, is_unixsock_path() is designed to detect such
cases, so, like any other code paths dealing with the same problem (psql
and libpq), use it rather than assuming that all valid paths are
prefixed with just a slash.
This issue has been found while testing the TAP tests of pg_upgrade
through the CI on Windows. This is a bug, but nobody has complained
about it since pg_upgrade exists so no backpatch is done, at least for
now.

pg_rewind generates and executes internally up to two commands to work
on the target cluster, depending on the options given by its caller:
- postgres -C to retrieve the value of restore_command, when using
-c/--restore-target-wal.
- postgres --single to enforce recovery once and get the target cluster
in a clean shutdown state.
Both commands have been applying incorrect quoting rules, which could
lead to failures when for example using a target data directory with
unexpected characters like CRLFs. Those commands are now generated with
PQExpBuffer, making use of string_utils.h to quote those commands as
they should. We may extend those commands in the future with more
options, so this makes any upcoming additions easier.
This is arguably a bug fix, but nobody has complained about the existing
code being a problem either, so no backpatch is done.

It was decided (refer to the Discussion link below) that the stats
collector is not an appropriate place to store the error information of
subscription workers.
This patch changes the pg_stat_subscription_workers view (introduced by
commit 8d74fc96db) so that it stores only statistics counters:
apply_error_count and sync_error_count, and has one entry for
each subscription. The removed error information such as error-XID and
the error message would be stored in another way in the future which is
more reliable and persistent.
After removing these error details, there is no longer any relation
information, so the subscription statistics are now a cluster-wide
statistics.
The patch also changes the view name to pg_stat_subscription_stats since
the word "worker" is an implementation detail that we use one worker for
one tablesync and one apply.

This change makes libpq apply the same private-key-file ownership
and permissions checks that we have used in the backend since commit
9a83564c5. Namely, that the private key can be owned by either the
current user or root (with different file permissions allowed in the
two cases). This allows system-wide management of key files, which
is just as sensible on the client side as the server, particularly
when the client is itself some application daemon.

This is pretty queasy-making on general principles, and the more so
once you notice that CommitTransactionCommand() is actually stomping
on the values saved by _SPI_commit(). It's okay as long as the

a larger assumption than I think we want to make, especially since

SPI_commit previously left it up to the caller to recover from any error
occurring during commit. Since that's complicated and requires use of
low-level xact.c facilities, it's not too surprising that no caller got
it right. Let's move the responsibility for cleanup into spi.c. Doing
that requires redefining SPI_commit as starting a new transaction, so
that it becomes equivalent to SPI_commit_and_chain except that you get
default transaction characteristics instead of preserving the prior
transaction's characteristics. We can make this pretty transparent
API-wise by redefining SPI_start_transaction() as a no-op. Callers
that expect to do something in between might be surprised, but
available evidence is that no callers do so.
Having made that API redefinition, we can fix this mess by having
SPI_commit[_and_chain] trap errors and start a new, clean transaction
before re-throwing the error. Likewise for SPI_rollback[_and_chain].
Some cleanup is also needed in AtEOXact_SPI, which was nowhere near
smart enough to deal with SPI contexts nested inside a committing
context.
While plperl and pltcl need no changes beyond removing their now-useless
SPI_start_transaction() calls, plpython needs some more work because it
hadn't gotten the memo about catching commit/rollback errors in the
first place. Such an error resulted in longjmp'ing out of the Python
interpreter, which leaks Python stack entries at present and is reported
to crash Python 3.11 altogether. Add the missing logic to catch such
errors and convert them into Python exceptions.
We are probably going to have to back-patch this once Python 3.11 ships,
but it's a sufficiently basic change that I'm a bit nervous about doing
so immediately. Let's let it bake awhile in HEAD first.

Since commit ffa2e4670, libpq resets conn->errorMessage only when
starting a new query. However, the later introduction of pipelining
requires a further refinement: the "start of query" isn't necessarily
when it's submitted to PQsendQueryStart. If we clear at that point
then we risk dropping text for an error that the application has not
noticed yet. Instead, when queuing a query while a previous query is
still in flight, leave errorMessage alone; reset it when we begin
to process the next query in pqPipelineProcessQueue.
Perhaps this should be back-patched to v14 where ffa2e4670 came in.
However I'm uncertain about whether it interacts with 618c16707.
In the absence of user complaints, leave v14 alone.

Formerly div_var() had "fast path" short division code that was
significantly faster when the divisor was just one base-NBASE digit,
but otherwise used long division.
This commit adds a new function div_var_int() that divides by an
arbitrary 32-bit integer, using the fast short division algorithm, and
updates both div_var() and div_var_fast() to use it for one and two
digit divisors. In the case of div_var(), this is slightly faster in
the one-digit case, because it avoids some digit array copying, and is
much faster in the two-digit case where it replaces long division. For
div_var_fast(), it is much faster in both cases because the main
div_var_fast() algorithm is optimised for larger inputs.
Additionally, optimise exp() and ln() by using div_var_int(), allowing
a NumericVar to be replaced by an int in a couple of places, most
notably in the Taylor series code. This produces a significant speedup
of exp(), ln() and the numeric_big regression test.

In the standard numeric division algorithm, the inner loop multiplies
the divisor by the next quotient digit and subtracts that from the
working dividend. As suggested by the original code comment, the
separate "carry" and "borrow" variables (from the multiplication and
subtraction steps respectively) can be folded together into a single
variable. Doing so significantly improves performance, as well as
simplifying the code.

This loop is basically the same as the inner loop of mul_var(), which
was auto-vectorized in commit 8870917623, but the compiler will only
consider auto-vectorizing the div_var_fast() loop if the assignment
target div[qi + i] is replaced by div_qi[i], where div_qi = &div[qi].
Additionally, since the compiler doesn't know that qdigit is
guaranteed to fit in a 16-bit NumericDigit, cast it to NumericDigit
before multiplying to make the resulting auto-vectorized code more
efficient (avoiding unnecessary multiplication of the high 16 bits).
While at it, per suggestion from Tom Lane, change var1digit in
mul_var() to be a NumericDigit rather than an int for the same
reason. This actually makes no difference with modern gcc, but it
might help other compilers generate more efficient assembly.

Perl can be convinced to execute user-defined code during compilation
of a plperl function (or at least a plperlu function). That's not
such a big problem as long as the activity is confined within the
Perl interpreter, and it's not clear we could do anything about that
anyway. However, if such code tries to use plperl's SPI functions,
we have a bigger problem. In the first place, those functions are
likely to crash because current_call_data->prodesc isn't set up yet.
In the second place, because it isn't set up, we lack critical info
such as whether the function is supposed to be read-only. And in
the third place, this path allows code execution during function
validation, which is strongly discouraged because of the potential
for security exploits. Hence, reject execution of the SPI functions
until compilation is finished.
While here, add check_spi_usage_allowed() calls to various functions
that hadn't gotten the memo about checking that. I think that perhaps
plperl_sv_to_literal may have been intentionally omitted on the grounds
that it was safe at the time; but if so, the addition of transforms
functionality changed that. The others are more recently added and
seem to be flat-out oversights.

Commit 49c9d9fc unified VACUUM VERBOSE and autovacuum logging. It
neglected to remove an old vacrel field that was only used by the old
VACUUM VERBOSE, so remove it now.
The previous num_tuples approach doesn't seem to have any real advantage
over the approach VACUUM VERBOSE takes now (also the approach used by
the autovacuum logging code), which is to show new_rel_tuples.
new_rel_tuples is the possibly-estimated total number of tuples left in
the table, whereas num_tuples meant the number of tuples encountered
during the VACUUM operation, after pruning, without regard for tuples
from pages skipped via the visibility map.
In passing, reorder a related vacrel field for consistency.
The buffer argument hasn't been used since the function was first added
by commit bbb6e559c4. The sibling heap_prepare_freeze_tuple function
doesn't have such an argument either. Remove it.
realloc() will return NULL on a failed reallocation, so the destination
pointer must be inspected to avoid null pointer dereference. Further,
assigning the return value to the source pointer leak the allocation in
the case of reallocation failure. Fix by using pg_realloc instead which
has full error handling.

This makes more consistent the SRF-related checks in the area of
PL/pgSQL, PL/Perl, PL/Tcl, pageinspect and some of the JSON worker
functions, making it easier to grep for the same error patterns through
the code, reducing a bit the translation work.
It is worth noting that each_worker_jsonb()/each_worker() in jsonfuncs.c
and pageinspect's brin_page_items() were doing a check on expectedDesc
that is not required as they fetch their tuple descriptor directly from
get_call_result_type(). This looks like a set of copy-paste errors that

This commit is a continuation of the changes begun in 07daca5, for any

The following set-returning functions have their logic simplified, to be
more consistent with other in-core areas:
- pg_prepared_statement()'s tuple descriptor is now created with
get_call_result_type() instead of being created from scratch, saving
from some duplication with pg_proc.dat.
- show_all_file_settings(), similarly, now uses get_call_result_type()
to build its tuple descriptor instead of creating it from scratch.
- pg_options_to_table() made use of a static routine called only once.
This commit removes this internal routine to make the function easier to
follow.
- pg_config() was using a unique logic style, doing checks on the tuple
descriptor passed down in expectedDesc, but it has no need to do so.
This switches the function to use a tuplestore with a tuple descriptor
retrieved from get_call_result_type(), instead.
This simplifies an upcoming patch aimed at refactoring the way
tuplestores are created and checked in set-returning functions, this
change making sense as its own independent cleanup by shaving some
code.

This feature adds row filtering for publication tables. When a publication
is defined or modified, an optional WHERE clause can be specified. Rows
that don't satisfy this WHERE clause will be filtered out. This allows a
set of tables to be partially replicated. The row filter is per table. A
new row filter can be added simply by specifying a WHERE clause after the
table name. The WHERE clause must be enclosed by parentheses.
The row filter WHERE clause for a table added to a publication that
publishes UPDATE and/or DELETE operations must contain only columns that
are covered by REPLICA IDENTITY. The row filter WHERE clause for a table
added to a publication that publishes INSERT can use any column. If the
row filter evaluates to NULL, it is regarded as "false". The WHERE clause
only allows simple expressions that don't have user-defined functions,
user-defined operators, user-defined types, user-defined collations,
non-immutable built-in functions, or references to system columns. These
restrictions could be addressed in the future.
If you choose to do the initial table synchronization, only data that
satisfies the row filters is copied to the subscriber. If the subscription
has several publications in which a table has been published with
different WHERE clauses, rows that satisfy ANY of the expressions will be
copied. If a subscriber is a pre-15 version, the initial table
synchronization won't use row filters even if they are defined in the
publisher.
The row filters are applied before publishing the changes. If the
subscription has several publications in which the same table has been
published with different filters (for the same publish operation), those
expressions get OR'ed together so that rows satisfying any of the
expressions will be replicated.
This means all the other filters become redundant if (a) one of the
publications have no filter at all, (b) one of the publications was
created using FOR ALL TABLES, (c) one of the publications was created
using FOR ALL TABLES IN SCHEMA and the table belongs to that same schema.
If your publication contains a partitioned table, the publication
parameter publish_via_partition_root determines if it uses the partition's
row filter (if the parameter is false, the default) or the root
partitioned table's row filter.
Psql commands \dRp+ and \d <table-name> will display any row filters.

"regress" is a new mode added to compute_query_id aimed at facilitating
regression testing when a module computing query IDs is loaded into the
backend, like pg_stat_statements. It works the same way as "auto",
meaning that query IDs are computed if a module enables it, except that
query IDs are hidden in EXPLAIN outputs to ensure regression output
stability.
Like any GUCs of the kind (force_parallel_mode, etc.), this new
configuration can be added to an instance's postgresql.conf, or just
passed down with PGOPTIONS at command level. compute_query_id uses an
enum for its set of option values, meaning that this addition ensures
ABI compatibility.
Using this new configuration mode allows installcheck-world to pass when

Commit 75d22069e tried to throw a warning for setting a custom GUC whose
prefix belongs to a previously-loaded extension, if there is no such GUC
defined by the extension. But that caused unstable behavior with
parallel workers, because workers don't necessarily load extensions and
GUCs in the same order their leader did. To make that work safely, we
have to completely disallow the case. We now actually remove any such
GUCs at the time of initial extension load, and then throw an error not
just a warning if you try to add one later. While this might create a
compatibility issue for a few people, the improvement in error-detection
capability seems worth it; it's hard to believe that there's any good
use-case for choosing such GUC names.

When cleaning up temporary objects during process exit the cleanup could fail
with:
FATAL: cannot fetch toast data without an active snapshot
The bug is caused by RemoveTempRelationsCallback() not setting up a
snapshot. If an object with toasted catalog data needs to be cleaned up,
init_toast_snapshot() could fail with the above error.
Most of the time however the the problem is masked due to cached catalog
snapshots being returned by GetOldestSnapshot(). But dropping an object can
cause catalog invalidations to be emitted. If no further catalog accesses are
necessary between the invalidation processing and the next toast datum
deletion, the bug becomes visible.
It's easy to miss this bug because it typically happens after clients
disconnect and the FATAL error just ends up in the log.
Luckily temporary table cleanup at the next use of the same temporary schema
or during DISCARD ALL does not have the same problem.
Fix the bug by pushing a snapshot in RemoveTempRelationsCallback(). Also add
isolation tests for temporary object cleanup, including objects with toasted
catalog data.
A future HEAD only commit will add an assertion trying to make this more
