Doc: mention executor memory usage for enable_partitionwise* GUCs
Prior to this commit, the docs for enable_partitionwise_aggregate and
enable_partitionwise_join mentioned the additional overheads enabling
these causes for the query planner, but they mentioned nothing about the
possible surge in work_mem-consuming executor nodes that could end up in
the final plan. Dimitrios reported the OOM killer intervened on his
query as a result of using enable_partitionwise_aggregate=on.
Here we adjust the docs to mention the possible increase in the number of
work_mem-consuming executor nodes that can appear in the final plan as a
result of enabling these GUCs.

SQL/JSON: Fix casting for integer EXISTS columns in JSON_TABLE
The current method of coercing the boolean result value of
JsonPathExists() to the target type specified for an EXISTS column,
which is to call the type's input function via json_populate_type(),
leads to an error when the target type is integer, because the
integer input function doesn't recognize boolean literal values as
valid.
Instead use the boolean-to-integer cast function for coercion in that
case so that using integer or domains thereof as type for EXISTS
columns works. Note that coercion for ON ERROR values TRUE and FALSE
already works like that because the parser creates a cast expression
including the cast function, but the coercion of the actual result

SQL/JSON: Some fixes to JsonBehavior expression casting
1. Remove the special case handling when casting the JsonBehavior
expressions to types with typmod, like
86d33987 did for the casting
of SQL/JSON constructor functions.
2. Fix casting for fixed-length character and bit string types by
using assignment-level casts. This is again similar to what
86d33987 did, but for ON ERROR / EMPTY expressions.
3. Use runtime coercion for the boolean ON ERROR constants so that
using fixed-length character string types, for example, for an
EXISTS column doesn't cause a "value too long for type
character(n)" when the parser tries to coerce the default ON ERROR
value "false" to that type, that is, even when clause is not
specified.
4. Simplify the conditions of when to use runtime coercion vs
creating the cast expression in the parser itself. jsonb-valued
expressions are now always coerced at runtime and boolean
expressions too if the target type is a string type for the
reasons mentioned above.
New tests are from a patch that Jian He posted. Outputs of some
existing tests change because the coercion now happens at runtime
instead of at parse time.

Count individual SQL commands in pg_restore's --transaction-size mode.
The initial implementation in commit
959b38d77 counted one action
per TOC entry (except for some special cases for multi-blob BLOBS
entries). This assumes that TOC entries are all about equally
complex, but it turns out that that assumption doesn't hold up very
well in binary-upgrade mode. For example, even after the previous
commit I was able to cause backend bloat with tables having many
inherited constraints. There may be other cases too. (Since no
serious problems have been reported with --single-transaction mode,
we can conclude that the backend copes well with psql's regular
restore scripts; but before
959b38d77 we never ran binary-upgrade
restores with multi-command transactions.)
To fix, count multi-command TOC entries as N actions, allowing the
transaction size to be scaled down when we hit a complex TOC entry.
Rather than add a SQL parser to pg_restore, approximate "multi
command" by counting semicolons in the TOC entry's defn string.
This will be fooled by semicolons appearing in string literals ---
but the error is in the conservative direction, so it doesn't seem
worth working harder. The biggest risk is with function/procedure
TOC entries, but we can just explicitly skip those.
(This is undoubtedly a hack, and maybe someday we'll be able to
revert it after fixing the backend's bloat issues or rethinking
what pg_dump emits in binary upgrade mode. But that surely isn't
a project for v17.)
Thanks to Alexander Korotkov for the let's-count-semicolons idea.

Reduce number of commands dumpTableSchema emits for binary upgrade.
Avoid issuing a separate SQL UPDATE command for each column when
directly manipulating pg_attribute contents in binary upgrade mode.
With the separate updates, we triggered a relcache invalidation with
each update. For a table with N columns, that causes O(N^2) relcache
bloat in txn_size mode because the table's newly-created relcache
entry can't be flushed till end of transaction. Reducing the number
of commands should make it marginally faster as well as avoiding that
problem.
While at it, likewise avoid issuing a separate UPDATE on pg_constraint
for each inherited constraint. This is less exciting, first because
inherited (non-partitioned) constraints are relatively rare, and
second because the backend has a good deal of trouble anyway with
restoring tables containing many such constraints, due to
MergeConstraintsIntoExisting being horribly inefficient. But it seems
more consistent to do it this way here too, and it surely can't hurt.
In passing, fix one place in dumpTableSchema that failed to use ONLY
in ALTER TABLE. That's not a live bug, but it's inconsistent.

cc.find_library will throw an error for a not found dependency as soon

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.

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.

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().

Ensure vacuum removes all visibly dead tuples older than OldestXmin
If vacuum fails to remove a tuple with xmax older than
VacuumCutoffs->OldestXmin and younger than GlobalVisState->maybe_needed,
it may attempt to freeze the tuple's xmax and then ERROR out in
pre-freeze checks with "cannot freeze committed xmax".
Fix this by having vacuum always remove tuples older than OldestXmin.
It is possible for GlobalVisState->maybe_needed to precede OldestXmin if
maybe_needed is forced to go backward while vacuum is running. This can
happen if a disconnected standby with a running transaction older than
VacuumCutoffs->OldestXmin reconnects to the primary after vacuum
initially calculates GlobalVisState and OldestXmin.
In back branches starting with 14, the first version using
GlobalVisState, failing to remove tuples older than OldestXmin during
pruning caused vacuum to infinitely loop in lazy_scan_prune(), as
investigated on this [1] thread. After
1ccc1e05ae removed the retry loop
in lazy_scan_prune() and stopped comparing tuples to OldestXmin, the
hang could no longer happen, but we could still attempt to freeze dead
tuples with xmax older than OldestXmin -- resulting in an ERROR.
Fix this by always removing dead tuples with xmax older than
VacuumCutoffs->OldestXmin. This is okay because the standby won't replay
the tuple removal until the tuple is removable. Thus, the worst that can
happen is a recovery conflict.

This, in turn, requires bumping XLOG_PAGE_MAGIC and, since the
Checkpoint is also stored in the control file, also
PG_CONTROL_VERSION. It's not great to do that so late in the release

A side effect of this patch is that, when a server with

summarization will no longer begin with the oldest WAL that still

instead of explicit casts to coerce the result of JSON constructor
functions to the specified or the default RETURNING type. Using
assignment-level casts fixes the problem that using explicit casts was
leading to the wrong typmod / length coercion behavior -- truncating
results longer than the specified length instead of erroring out --
which
c2d93c3802b aimed to solve.
That restricts the set of allowed target types to string types, the
same set that's currently allowed.

Fix lost Windows socket EOF events.
Winsock only signals an FD_CLOSE event once if the other end of the
socket shuts down gracefully. Because each WaitLatchOrSocket() call
constructs and destroys a new event handle every time, with unlucky
timing we can lose it and hang. We get away with this only if the other
end disconnects non-gracefully, because FD_CLOSE is repeatedly signaled
in that case.
To fix this design flaw in our Windows socket support fundamentally,
we'd probably need to rearchitect it so that a single event handle
exists for the lifetime of a socket, or switch to completely different
multiplexing or async I/O APIs. That's going to be a bigger job
and probably wouldn't be back-patchable.

Fix ALTER TABLE DETACH for inconsistent indexes
When a partitioned table has an index that doesn't support a constraint,
but a partition has an equivalent index that does, then a DETACH
operation would misbehave: a crash in assertion-enabled systems (because
we fail to find the constraint in the parent that we expect to), or a
broken coninhcount value (-1) in production systems (because we blindly
believe that we've successfully detached the parent).
While we should reject an ATTACH of a partition with such an index, we
have failed to do so in existing releases, so adding an error in stable
releases might break the (unlikely) existing applications that rely on
this behavior. At this point I don't even want to reject them in
master, because it'd break pg_upgrade if such databases exist, and there
would be no easy way to fix existing databases without expensive index
rebuilds.
(Later on we could add ALTER TABLE ... ADD CONSTRAINT USING INDEX to
partitioned tables, which would allow the user to fix such patterns. At
that point we could add more restrictions to prevent the problem from
its root.)
Also, add a test case that leaves one table in this condition, so that
we can verify that pg_upgrade continues to work if we later decide to
change the policy on the master branch.

This happens because the INSERT before slot synchronization results in the

before the xmin of the physical slot on the primary catches up via
hot_standby_feedback, the test has created a logical slot that got some
prior value of catalog_xmin.

Fix possibility of logical decoding partial transaction changes.
When creating and initializing a logical slot, the restart_lsn is set
to the latest WAL insertion point (or the latest replay point on
standbys). Subsequently, WAL records are decoded from that point to
find the start point for extracting changes in the
DecodingContextFindStartpoint() function. Since the initial
restart_lsn could be in the middle of a transaction, the start point
must be a consistent point where we won't see the data for partial
transactions.
Previously, when not building a full snapshot, serialized snapshots
were restored, and the SnapBuild jumps to the consistent state even
while finding the start point. Consequently, the slot's restart_lsn
and confirmed_flush could be set to the middle of a transaction. This
could lead to various unexpected consequences. Specifically, there
were reports of logical decoding decoding partial transactions, and
assertion failures occurred because only subtransactions were decoded
without decoding their top-level transaction until decoding the commit
record.
To resolve this issue, the changes prevent restoring the serialized
snapshot and jumping to the consistent state while finding the start
point.
On v17 and HEAD, a flag indicating whether snapshot restores should be
skipped has been added to the SnapBuild struct, and SNAPBUILD_VERSION
has been bumpded.
On backbranches, the flag is stored in the LogicalDecodingContext
instead, preserving on-disk compatibility.

Fix right-anti-joins when the inner relation is proven unique
For an inner_unique join, we always assume that the executor will stop
scanning for matches after the first match. Therefore, for a mergejoin
that is inner_unique and whose mergeclauses are sufficient to identify a
match, we set the skip_mark_restore flag to true, indicating that the
executor need not do mark/restore calls. However, merge-right-anti-join
did not get this memo and continues scanning the inner side for matches
after the first match. If there are duplicates in the outer scan, we
may incorrectly skip matching some inner tuples, which can lead to wrong
results.
Here we fix this issue by ensuring that merge-right-anti-join also
advances to next outer tuple after the first match in inner_unique
cases. This also saves cycles by avoiding unnecessary scanning of inner
tuples after the first match.
Although hash-right-anti-join does not suffer from this wrong results
issue, we apply the same change to it as well, to help save cycles for
the same reason.
Per bug #18522 from Antti Lampinen, and bug #18526 from Feliphe Pozzer.
Back-patch to v16 where right-anti-join was introduced.

Re-enable autoruns for for cmd.exe on Windows
This acts as a revert of
b83747a8a65b and
9886744a361b. As pointed out
by Noah, HEAD and REL_17_STABLE are in a weird state where the code
paths adding /D would limit the spawn of child processes, but we still
have code paths where the spawn of more than one child process would be
possible.
Let's remove these /D switches for now, to bring back the code into a
state consistent with how autorun is configured on a Windows host.
