The description of this GUC provides a list of the situations where
full-page writes are generated. However, it is not completely exact,
mentioning only the cases where full_page_writes=on or base backups. It
is possible to generate full-page writes in more situations than these
two, making the description confusing as it implies that no other cases
exist.
The description is slightly reworded to take into account that other
cases are possible, without mentioning them directly to minimize the
maintenance burden should FPWs be generated in more contexts in the
future.

If we error out during execution of a SQL-language function, we will
often leave behind non-null pointers in its SQLFunctionCache's cplan
and eslist fields. This is problematic if the SQLFunctionCache is
re-used, because those pointers will point at resources that were
released during error cleanup. This problem escaped detection so far
because ordinarily we won't re-use an FmgrInfo+SQLFunctionCache struct
after a query error. However, in the rather improbable case that
someone implements an opclass support function in SQL language, there
will be long-lived FmgrInfos for it in the relcache, and then the
problem is reachable after the function throws an error.
To fix, add a flag to SQLFunctionCache that tracks whether execution
escapes out of fmgr_sql, and clear out the relevant fields during
init_sql_fcache if so. (This is going to need more thought if we ever
try to share FMgrInfos across threads; but it's very far from being
the only problem such a project will encounter, since many functions
regard fn_extra as being query-local state.)
This broke at commit 0313c5dc6; before that we did not try to re-use
SQLFunctionCache state across calls. Hence, back-patch to v18.

Some replication slot manipulations (logical decoding via SQL,
advancing) were failing an assertion when releasing a slot in
single-user mode, because active_pid was not set in a ReplicationSlot
when its slot is acquired.
ReplicationSlotAcquire() has some logic to be able to work with the
single-user mode. This commit sets ReplicationSlot->active_pid to
MyProcPid, to let the slot-related logic fall-through, considering the
single process as the one holding the slot.
Some TAP tests are added for various replication slot functions with the
single-user mode, while on it, for slot creation, drop, advancing, copy
and logical decoding with multiple slot types (temporary, physical vs
logical). These tests are skipped on Windows, as direct calls of
postgres --single would fail on permission failures. There is no
platform-specific behavior that needs to be checked, so living with this
restriction should be fine. The CI is OK with that, now let's see what
the buildfarm tells.

vacuumdb should follow the behavior of the underlying VACUUM and ANALYZE
commands. When --analyze-only is used, it ought to analyze regular tables,
materialized views, and partitioned tables, just as ANALYZE (with no explicit
target tables) does. Otherwise, it should only process regular tables and
materialized views, since VACUUM skips partitioned tables when no targets
are given.
Previously, vacuumdb --analyze-only skipped partitioned tables. This was
inconsistent, and also inconvenient after pg_upgrade, where --analyze-only
is typically used to gather missing statistics.
This commit fixes the behavior so that vacuumdb --analyze-only also processes
partitioned tables. As a result, both vacuumdb --analyze-only and
ANALYZE (with no explicit targets) now analyze regular tables,
partitioned tables, and materialized views, but not foreign tables.
Because this is a nontrivial behavior change, it is applied only to master.

The DROP SUBSCRIPTION command performs several operations: it stops the
subscription workers, removes subscription-related entries from system
catalogs, and deletes the replication slot on the publisher server.
Previously, this command acquired an AccessExclusiveLock on
pg_subscription before initiating these steps.
However, while holding this lock, the command attempts to connect to the
publisher to remove the replication slot. In cases where the connection is
made to a newly created database on the same server as subscriber, the
cache-building process during connection tries to acquire an
AccessShareLock on pg_subscription, resulting in a self-deadlock.
To resolve this issue, we reduce the lock level on pg_subscription during
DROP SUBSCRIPTION from AccessExclusiveLock to RowExclusiveLock. Earlier,
the higher lock level was used to prevent the launcher from starting a new
worker during the drop operation, as a restarted worker could become
orphaned.
Now, instead of relying on a strict lock, we acquire an AccessShareLock on
the specific subscription being dropped and re-validate its existence
after acquiring the lock. If the subscription is no longer valid, the
worker exits gracefully. This approach avoids the deadlock while still
ensuring that orphan workers are not created.

There are two implementation techniques for semijoins: one uses the
JOIN_SEMI jointype, where the executor emits at most one matching row
per left-hand side (LHS) row; the other unique-ifies the right-hand
side (RHS) and then performs a plain inner join.
The latter technique currently has some drawbacks related to the
unique-ification step.
* Only the cheapest-total path of the RHS is considered during
unique-ification. This may cause us to miss some optimization
opportunities; for example, a path with a better sort order might be
overlooked simply because it is not the cheapest in total cost. Such
a path could help avoid a sort at a higher level, potentially
resulting in a cheaper overall plan.
* We currently rely on heuristics to choose between hash-based and
sort-based unique-ification. A better approach would be to generate
paths for both methods and allow add_path() to decide which one is
preferable, consistent with how path selection is handled elsewhere in
the planner.
* In the sort-based implementation, we currently pay no attention to
the pathkeys of the input subpath or the resulting output. This can
result in redundant sort nodes being added to the final plan.
This patch improves semijoin planning by creating a new RelOptInfo for
the RHS rel to represent its unique-ified version. It then generates
multiple paths that represent elimination of distinct rows from the
RHS, considering both a hash-based implementation using the cheapest
total path of the original RHS rel, and sort-based implementations
that either exploit presorted input paths or explicitly sort the
cheapest total path. All resulting paths compete in add_path(), and
those deemed worthy of consideration are added to the new RelOptInfo.
Finally, the unique-ified rel is joined with the other side of the
semijoin using a plain inner join.
As a side effect, most of the code related to the JOIN_UNIQUE_OUTER
and JOIN_UNIQUE_INNER jointypes -- used to indicate that the LHS or
RHS path should be made unique -- has been removed. Besides, the
T_Unique path now has the same meaning for both semijoins and upper
DISTINCT clauses: it represents adjacent-duplicate removal on
presorted input. This patch unifies their handling by sharing the
same data structures and functions.
This patch also removes the UNIQUE_PATH_NOOP related code along the
way, as it is dead code -- if the RHS rel is provably unique, the
semijoin should have already been simplified to a plain inner join by
analyzejoins.c.

easier the manipulation of metadata related to sequences. The knowledge
about "log_cnt" is replaced with a more general "reset_state" flag, to

This test exercises the corner case in toast_save_datum() where CLUSTER
operations encounter duplicated TOAST references, reusing the existing
TOAST data instead of creating redundant copies.
During table rewrites like CLUSTER, both live and recently-dead versions
of a row may reference the same TOAST value. When copying the second or
later version of such a row, the system checks if a TOAST value already
exists in the new TOAST table using toastrel_valueid_exists(). If
found, toast_save_datum() sets data_todo = 0 so as redundant data is not
stored, ensuring only one copy of the TOAST value exists in the new
table.
The test relies on a combination of UPDATE, CLUSTER, and checks of the
TOAST values used before and after the relation rewrite, to make sure
that the same values are reused across the rewrite.

case keeps working should we mess with this area of the code.

The SQL test added in this commit check a specific code path that had no
coverage until now. When a TOAST datum is rewritten, toast_save_datum()
has a dedicated path to make sure that a new value is allocated if it
does not exist on the TOAST table yet.
This test uses a trick with PLAIN and EXTERNAL storage, with a tuple
large enough to be toasted and small enough to fit on a page. It is
initially stored in plain more, and the rewrite forces the tuple to be
stored externally. The key point is that there is no value allocated
during the initial insert, and that there is one after the rewrite. A
second pattern checked is the reuse of the same value across rewrites,
using \gset.
A set of patches under discussion is messing up with this area of the
code, so this makes sure that such rewrite cases remain consistent
across the board.

Make sure the memory allocated by make_absolute_path() is freed
when SelectConfigFiles() fails. Since all the callers will exit
immediately in that case, there's no practical gain here, but
silencing Valgrind leak complaints seems useful. In any case,
it was inconsistent that only one of the failure exits did this.

This function uses an argument named "maxsize" that is only used in
assertions, being set once outside the assertion area. Recent gcc
versions with -Wunused-but-set-parameter complain about a warning when
building without assertions enabled, because of that.
In order to fix this issue, PG_USED_FOR_ASSERTS_ONLY is added to the
function argument of SerializeClientConnectionInfo(), which is the first
time we are doing so in the tree. The CI is fine with the change, but
let's see what the buildfarm has to say on the matter.

Commit 2633dae2e4 standardized LSN formatting but mistakenly changed
the logical snapshot filename format in SnapBuildSnapshotExists() from
"%X-%X.snap" to "%08X-%08X.snap". Other code still used the original
"%X-%X.snap" format, causing the replication slot synchronization worker
to fail to find existing snapshot files and produce excessive log messages.
This commit restores the original "%X-%X.snap" format
in SnapBuildSnapshotExists() to resolve the issue.

Remove conditionally-compiled code for the other case.
Replace uses of FLOAT8PASSBYVAL with constant "true", mainly because
it was quite confusing in cases where the type we were dealing with
wasn't float8.
I left the associated pg_control and Pg_magic_struct fields in place.
Perhaps we should get rid of them, but it would save little, so it
doesn't seem worth thinking hard about the compatibility implications.
I just labeled them "vestigial" in places where that seemed helpful.

Remove conditionally-compiled code for smaller Datum widths,
and simplify comments that describe cases no longer of interest.
I also fixed up a few more places that were not using
DatumGetIntXX where they should, and made some cosmetic
adjustments such as using sizeof(int64) not sizeof(Datum)
in places where that fit better with the surrounding code.
One thing I remembered while preparing this part is that SP-GiST
stores pass-by-value prefix keys as Datums, so that the on-disk
representation depends on sizeof(Datum). That's even more
unfortunate than the existing commentary makes it out to be,
because now there is a hazard that the change of sizeof(Datum)
will break SP-GiST indexes on 32-bit machines. It appears that
there are no existing SP-GiST opclasses that are actually
affected; and if there are some that I didn't find, the number
of installations that are using them on 32-bit machines is
doubtless tiny. So I'm proceeding on the assumption that we
can get away with this, but it's something to worry about.
(gininsert.c looks like it has a similar problem, but it's okay
because the "tuples" it's constructing are just transient data
within the tuplesort step. That's pretty poorly documented
though, so I added some comments.)

This patch makes sizeof(Datum) be 8 on all platforms including
32-bit ones. The objective is to allow USE_FLOAT8_BYVAL to be true
everywhere, and in consequence to remove a lot of code that is
specific to pass-by-reference handling of float8, int8, etc. The
code for abbreviated sort keys can be simplified similarly. In this
way we can reduce the maintenance effort involved in supporting 32-bit
platforms, without going so far as to actually desupport them. Since
Datum is strictly an in-memory concept, this has no impact on on-disk
storage, though an initdb or pg_upgrade will be needed to fix affected
catalog entries.
We have required platforms to support [u]int64 for ages, so this
breaks no supported platform. We can expect that this change will
make 32-bit builds a bit slower and more memory-hungry, although being
able to use pass-by-value handling of 8-byte types may buy back some
of that. But we stopped optimizing for 32-bit cases a long time ago,
and this seems like just another step on that path.
This initial patch simply forces the correct type definition and
USE_FLOAT8_BYVAL setting, and cleans up a couple of minor compiler
complaints that ensued. This is sufficient for testing purposes.
In the wake of a bunch of Datum-conversion cleanups by Peter
Eisentraut, this now compiles cleanly with gcc on a 32-bit platform.
(I'd only tested the previous version with clang, which it turns out
is less picky than gcc about width-changing coercions.)
There is a good deal of now-dead code that I'll remove in separate
follow-up patches.
A catversion bump is required because this affects initial catalog
contents (on 32-bit machines) in two ways: pg_type.typbyval changes
for some built-in types, and Const nodes in stored views/rules will
now have 8 bytes not 4 for pass-by-value types.

Currently the pdb file for libpq and some other libraries are named the same
for the static and shared libraries. That has been the case for a long time,
but recently started failing, after an image update started using a newer
ninja version. The issue is not itself caused by ninja, but just made visible,
as the newer version optimizes the build order and builds the shared libpq
earlier than the static library. Previously both static and shared libraries
were built at the same time, which prevented msvc from detecting the issue.
When using /DEBUG:FASTLINK pdb files cannot be updated, triggering the error.
We were using /DEBUG:FASTLINK due to running out of memory in the past, but
that was when using container based CI images, rather than full VMs.
This isn't really the correct fix (that'd be to deconflict the pdb file
names), but we'd like to get CI to become green again, and a proper fix (in
meson) will presumably take longer.
