The logical decoding infrastructure needs to know which top-level
transaction the subxact belongs to, in order to decode all the
changes. Until now that might be delayed until commit, due to the
caching (GPROC_MAX_CACHED_SUBXIDS), preventing features requiring
incremental decoding.
So we also write the assignment info into WAL immediately, as part
of the next WAL record (to minimize overhead) only when wal_level=logical.
We can not remove the existing XLOG_XACT_ASSIGNMENT WAL as that is
required for avoiding overflow in the hot standby snapshot.
Bump XLOG_PAGE_MAGIC, since this introduces XLR_BLOCK_ID_TOPLEVEL_XID.

Valgrind builds with assertions enabled sometimes perform a
theoretically unsafe page access inside an assertion in
heapam_tuple_lock(). This happened when the eval-plan-qual isolation
test ran one of the permutations added by commit a2418f9e23.
Avoid complaints from Valgrind by moving the assertion ever so slightly.
This is minor cleanup for commit 1e0dfd16, which added Valgrind buffer
access instrumentation.
No backpatch, since this only happens within an assertion, and seems
very unlikely to cause any real problems even with assert-enabled
builds.
Make PinBuffer() mark buffers as defined to Valgrind unconditionally,
including when the buffer header spinlock must be acquired. Failure to
handle that case could lead to false positive reports from Valgrind.
This theoretically creates a risk that we'll mark buffers defined even
when external callers don't end up with a buffer pin. That seems
perfectly acceptable, though, since in general we make no guarantees
about buffers that are unsafe to access being reliably marked as unsafe.
Oversight in commit 1e0dfd16, which added valgrind buffer access
instrumentation.
Due to the layout of this catalog, subslotname has to be explicitly
marked BKI_FORCE_NULL, else initdb will default to the assumption
that it's non-nullable. Since, in fact, CREATE/ALTER SUBSCRIPTION
will store null values there, the existing marking is just wrong,
and has been since this catalog was invented.
We haven't noticed because not much in the system actually depends
on attnotnull being truthful. However, JIT'ed tuple deconstruction
does depend on that in some cases, allowing crashes or wrong answers
in queries that inspect pg_subscription. Commit 9de77b545 quite
accidentally exposed this on the buildfarm members that force JIT
activation.
Back-patch to v13. The problem goes further back, but we cannot
force initdb in released branches, so some klugier solution will
be needed there. Before working on that, push this simple fix
to try to get the buildfarm back to green.

This patch adds a "binary" option to CREATE/ALTER SUBSCRIPTION.
When that's set, the publisher will send data using the data type's
typsend function if any, rather than typoutput. This is generally
faster, if slightly less robust.
As committed, we won't try to transfer user-defined array or composite

The term "hash_mem" will take on new significance when pending work to
add a new hash_mem_multiplier GUC is committed. Rename a local variable
that happens to have been called hash_mem now to avoid confusion.
Teach Valgrind memcheck to maintain the "defined-ness" of each shared
buffer based on whether the backend holds at least one pin at the point
it is accessed by access method code. Bugs like the one fixed by commit
b0229f26 can be detected using this new instrumentation.
Note that backends running with Valgrind naturally have their own
independent ideas about whether any given byte in shared memory is safe
or unsafe to access. There is no risk that concurrent access by
multiple backends to the same shared memory will confuse Valgrind's
instrumentation, because everything already works at the process level
(or at the memory mapping level, if you prefer).

pg_dump produces custom-format archive files that lack data offsets
when it is unable to seek its output. Up to now that's been a hazard
for pg_restore. But if pg_restore is able to seek in the archive
file, there is no reason to throw up our hands when asked to restore
data blocks out of order. Instead, whenever we are searching for a
data block, record the locations of the blocks we passed over (that
is, fill in the missing data-offset fields in our in-memory copy of
the TOC data). Then, when we hit a case that requires going
backwards, we can just seek back.
Also track the furthest point that we've searched to, and seek back
to there when beginning a search for a new data block. This avoids
possible O(N^2) time consumption, by ensuring that each data block
is examined at most twice. (On Unix systems, that's at most twice
per parallel-restore job; but since Windows uses threads here, the
threads can share block location knowledge, reducing the amount of
duplicated work.)
We can also improve the code a bit by using fseeko() to skip over
data blocks during the search.
This is all of some use even in simple restores, but it's really
significant for parallel pg_restore. In that case, we require
seekability of the input already, and we will very probably need
to do out-of-order restores.
Back-patch to v12, as this fixes a regression introduced by commit
548e50976. Before that, parallel restore avoided requesting
out-of-order restores, so it would work on a data-offset-less
archive. Now it will again.
Ideally this patch would include some test coverage, but there are
other open bugs that need to be fixed before we can extend our
coverage of parallel restore very much. Plan to revisit that later.

We do not really need to track the file position by hand. We were
already relying on ftello() whenever the archive file is seekable,
while if it's not seekable we don't need the file position info
anyway because we're not going to be able to re-write the TOC.
Moreover, that tracking was buggy since it failed to account for
the effects of fseeko(). Somewhat remarkably, that seems not to
have made for any live bugs up to now. We could fix the oversights,
but it seems better to just get rid of the whole error-prone mess.
In itself this is merely code cleanup. However, it's necessary
infrastructure for an upcoming bug-fix patch (because that code
*does* need valid file position after fseeko). The bug fix
needs to go back as far as v12; hence, back-patch that far.

There is no advantage to attempting deduplication for a unique index
during CREATE INDEX, since there cannot possibly be any duplicates.
Doing so wastes cycles due to unnecessary copying. Make sure that we
avoid it consistently.
We already avoided unique index deduplication in the case where there
were some spool2 tuples to merge. That didn't account for the fact that
spool2 is removed early/unset in the common case where it has no tuples
that need to be merged (i.e. it failed to account for the "spool2 turns
out to be unnecessary" optimization in _bt_spools_heapscan()).

pg_test_fsync has always opened files using the text mode on Windows, as
this is the default mode used if not enforced by _setmode().
This fixes a failure when running pg_test_fsync down to 12 because
O_DSYNC and the text mode are not able to work together nicely. We
fixed the handling of O_DSYNC in 12~ for the tool by switching to the
concurrent-safe version of fopen() in src/port/ with 0ba06e0. And
40cfe86, by enforcing the text mode for compatibility reasons if O_TEXT
or O_BINARY are not specified by the caller, broke pg_test_fsync. For
all versions, this avoids any translation overhead, and pg_test_fsync
should test binary writes, so it is a gain in all cases.
Note that O_DSYNC is still not handled correctly in ~11, leading to
pg_test_fsync to show insanely high numbers for open_datasync() (using
this property it is easy to notice that the binary mode is much
faster). This would require a backpatch of 0ba06e0 and 40cfe86, which
could potentially break existing applications, so this is left out.
There are no TAP tests for this tool yet, so I have checked all builds
manually using MSVC. We could invent a new option to run a single
transaction instead of using a duration of 1s to make the tests a
maximum short, but this is left as future work.

When working with an online source cluster, pg_rewind gets a list of all
the files in the source data directory using a WITH RECURSIVE query,
returning a NULL result for a file's metadata if it gets removed between
the moment it is listed in a directory and the moment its metadata is
obtained with pg_stat_file() (say a recycled WAL segment). The query
result was processed in such a way that for each tuple we checked only
that the first file's metadata was NULL. This could have two
consequences, both resulting in a failure of the rewind:
- If the first tuple referred to a removed file, all files from the
source would be ignored.
- Any file actually missing would not be considered as such.
While on it, rework slightly the code so as no values are saved if we

* pg_identify_object_as_address()
The set of APIs managing object addresses for all object types are made
smarter by gaining a new argument "missing_ok" that allows any caller to
control if an error is raised or not on an undefined object. The SQL
functions listed above are changed to handle the case where an object is
missing.
Regression tests are added for all object types for the cases where
these are undefined. Before this commit, these cases failed with cache
lookup errors, and now they basically return NULL (minus the name of the
object type requested).

reparameterize_path_by_child() failed to reparameterize BitmapAnd
and BitmapOr paths. This matters only if such a path is chosen as
the inside of a nestloop partition-wise join, where we have to pass
in parameters from the outside of the nestloop. If that did happen,
we generated a bad plan that would likely lead to crashes at execution.
This is not entirely reparameterize_path_by_child()'s fault though;
it's the victim of an ancient decision (my ancient decision, I think)
to not bother filling in param_info in BitmapAnd/Or path nodes. That
caused the function to believe that such nodes and their children
contain no parameter references and so need not be processed.
In hindsight that decision looks pretty penny-wise and pound-foolish:
while it saves a few cycles during path node setup, we do commonly
need the information later. In particular, by reversing the decision
and requiring valid param_info data in all nodes of a bitmap path
tree, we can get rid of indxpath.c's get_bitmap_tree_required_outer()
function, which computed the data on-demand. It's not unlikely that
that nets out as a savings of cycles in many scenarios. A couple
of other things in indxpath.c can be simplified as well.
While here, get rid of some cases in reparameterize_path_by_child()
that are visibly dead or useless, given that we only care about
reparameterizing paths that can be on the inside of a parameterized
nestloop. This case reminds one of the maxim that untested code
probably does not work, so I'm unwilling to leave unreachable code
in this function. (I did leave the T_Gather case in place even
though it's not reached in the regression tests. It's not very
clear to me when the planner might prefer to put Gather below
rather than above a nestloop, but at least in principle the case
might be interesting.)

load_external_function() and related functions returned PGFunction,
even though not necessarily all callers are looking for a function of

around dlsym(), change to return void * just like dlsym().
In dynahash.c, we are using strlcpy() where a function with a

comment there explains, but the cast needs to be augmented to avoid
the warning.
In PL/Python, methods all need to be cast to PyCFunction, per Python
API, but this now runs afoul of these warnings. (This issue also
exists in core CPython.)
To fix the second and third case, we add a new type pg_funcptr_t that
is defined specifically so that gcc accepts it as a special function
pointer that can be cast to any other function pointer without the
warning.
Also add -Wcast-function-type to the standard warning flags, subject

An ALTER TABLE to validate a foreign key in which another subcommand
already caused a pending table rewrite could fail due to ALTER TABLE
attempting to validate the foreign key before the actual table rewrite
takes place. This situation could result in an error such as:
ERROR: could not read block 0 in file "base/nnnnn/nnnnn": read only 0 of 8192 bytes
The failure here was due to the SPI call which validates the foreign key
trying to access an index which is yet to be rebuilt.
Similarly, we also incorrectly tried to validate CHECK constraints before
the heap had been rewritten.
The fix for both is to delay constraint validation until phase 3, after
the table has been rewritten. For CHECK constraints this means a slight
behavioral change. Previously ALTER TABLE VALIDATE CONSTRAINT on
inheritance tables would be validated from the bottom up. This was
different from the order of evaluation when a new CHECK constraint was
added. The changes made here aligns the VALIDATE CONSTRAINT evaluation
order for inheritance tables to be the same as ADD CONSTRAINT, which is

The qual pushdown logic assumed that all Vars in a restriction clause

build, there might be no ill effects (if qual_is_pushdown_safe decided
the qual was unsafe anyway), or we could get failures later due to

Parallel pg_restore has always supposed that ACL items for different
objects are independent and can be restored in parallel without
conflicts. However, there is one case where this fails: because
REVOKE on a table is defined to also revoke the privilege(s) at
column level, we can't restore per-column ACLs till after we restore
any table-level privileges on their table. Failure to honor this
restriction can lead to "tuple concurrently updated" errors during
parallel restore, or even to the per-column ACLs silently disappearing
because the table-level REVOKE is executed afterwards.
To fix, add a dependency from each column-level ACL item to its table's
ACL item, if there is one. Note that this doesn't fix the hazard
for pre-existing archive files, only for ones made with a corrected
pg_dump. Given that the bug's been there quite awhile without
field reports, I think this is acceptable.
This requires changing the API of pg_dump's dumpACL() function.

"relkind" normally refers to the char field from pg_class. However, in
the parse nodes AlterTableStmt and CreateTableAsStmt, "relkind" was used
for a field of type enum ObjectType, that could refer to other object
types than those possible for a relkind. Such fields being usually
named "objtype", switch the name in both structures to make things more
consistent. Note that this led to some confusion in functions that
also operate on a RangeTableEntry object, which also has a field named
"relkind".
This naming goes back to commit 09d4e96, where only OBJECT_TABLE and
