This way we don't need RANLIB anymore, making it a bit simpler for the meson
build to generate Makefile.global for PGXS compatibility.
FreeBSD, NetBSD, OpenBSD, the only platforms where we didn't use AROPT=crs,
all have supported the 's' option for a long time.
On macOS we ran ranlib after installing a static library. This was added a
long time ago, in 58ad65ec2d. I cannot reproduce an issue in more recent
macOS versions. This is removed now.
Based on discussion with Tom, I left the 'touch' at the end of static
libraries generation, added in 826eff57c4, in place. While it looks like
current versions of Apple's ar/ranlib don't need it, it was needed not too
long ago.

There are a number of bugs in this area. Two of them are fixed here,
namely:
1. get_relation_idx_constraint_oid does not restrict the type of
constraint that's returned, so with sufficient bad luck it can
return the OID of a foreign key constraint. This has the effect that
a primary key in a partition can end up as a child of a foreign key,
which makes no sense (it needs to be the child of the equivalent
primary key.)
Change the API contract so that only index-backed constraints are
returned, mimicking get_constraint_index().
2. Both CloneFkReferenced and CloneFkReferencing clone a
self-referencing foreign key, so the partition ends up with
a duplicate foreign key. Change the former function to ignore such
constraints.
Add some tests to verify that things are better now. (However, these
new tests show some additional misbehavior that will be fixed later --
namely that there's a constraint marked NOT VALID.)
Backpatch to 12, where these constraints are possible at all.

Commit c6e0fe1f2 was a shade too trusting that any pointer passed
to pfree, repalloc, etc will point at a valid chunk. Notably,
passing a pointer that was actually obtained from malloc tended
to result in obscure assertion failures, if not worse. (On FreeBSD
I've seen such mistakes take down the entire cluster, seemingly as
a result of clobbering shared memory.)
To improve matters, extend the mcxt_methods[] array so that it
has entries for every possible MemoryContextMethodID bit-pattern,
with the currently unassigned ID codes pointing to error-reporting
functions. Then, fiddle with the ID assignments so that patterns
likely to be associated with bad pointers aren't valid ID codes.
In particular, we should avoid assigning bit patterns 000 (zeroed
memory) and 111 (wipe_mem'd memory).
It turns out that on glibc (Linux), malloc uses chunk headers that
have flag bits in the same place we keep MemoryContextMethodID,
and that the bit patterns 000, 001, 010 are the only ones we'll
see as long as the backend isn't threaded. So we can have very
robust detection of pfree'ing a malloc-assigned block on that
platform, at least so long as we can refrain from using up those
ID codes. On other platforms, we don't have such a good guarantee,
but keeping 000 reserved will be enough to catch many such cases.
While here, make GetMemoryChunkMethodID() local to mcxt.c, as there
seems no need for it to be exposed even in memutils_internal.h.
Patch by me, with suggestions from Andres Freund and David Rowley.

This substantially speeds up building for windows, due to the vast amount of
headers included via windows.h. A cross build from linux targetting mingw goes
from
994.11user 136.43system 0:31.58elapsed 3579%CPU
to
422.41user 89.05system 0:14.35elapsed 3562%CPU
The wins on windows are similar-ish (but I don't have a system at hand just
now for actual numbers). Targetting other operating systems the wins are far
smaller (tested linux, macOS, FreeBSD).
For now precompiled headers are disabled by default, it's not clear how well
they work on all platforms. E.g. on FreeBSD gcc doesn't seem to have working
support, but clang does.
When doing a full build precompiled headers are only beneficial for targets
with multiple .c files, as meson builds a separate precompiled header for each
target (so that different compilation options take effect). This commit
therefore only changes target with at least two .c files to use precompiled
headers.
Because this commit adds b_pch=false to the default_options new build
directories will have precompiled headers disabled by default, however
existing build directories will continue use the default value of b_pch, which
is true.
Note that using precompiled headers with ccache requires setting
CCACHE_SLOPPINESS=pch_defines,time_macros to get hits.

When using precompiled headers, we cannot pre-define macros for the system
headers from within .c files, as headers are already processed before
the #define in the C file is reached. But we can pre-define using
-DFD_SETSIZE, as long as that's also used when building the precompiled header.
A few files #define FD_SETSIZE 1024 on windows, as the default is only 64. I
am hesitant to change FD_SETSIZE globally on windows, due to
src/backend/port/win32/socket.c using it to size on-stack arrays. Instead add
-DFD_SETSIZE=1024 when building the specific targets needing it.
We likely should move away from using select() in those places, but that's a

MemoryContextContains is no longer reliable in the wake of c6e0fe1f2,
because there's no longer very much redundancy in chunk headers.
(It wasn't *completely* reliable even before that, as there was a
chance of a false positive if you passed it something that didn't
point to an mcxt chunk at all. But it was generally good enough.)
Hence, remove it. There is no remaining core code that requires it.
Extensions that have been using it might be able to substitute a
test like "GetMemoryChunkContext(ptr) == context", recognizing that
this explicitly requires that the pointer point to some chunk.

MemoryContextContains is no longer reliable in the wake of c6e0fe1f2,
so we need to get rid of these uses.
It appears that there's no really good reason to force the result of
an aggregate's finalfn or serialfn to be allocated in the per-tuple
context. The only other plausible case is that the result points to
or into the aggregate's transition value, and that's fine because it
will last as long as we need it to. (This conclusion depends on the
assumption that finalfns are not allowed to scribble on the transition
value, but we've long required that.) So we can just drop the
MemoryContextContains plus datumCopy business, although we do need
to take care to not return a read-write pointer when the transition
value is an expanded datum.
Likewise, we don't really need to force the result of a window
function to be in the output context. In this case, the plausible
alternative is that it's pointing into the temporary tuple slot used
by WinGetFuncArgInPartition or WinGetFuncArgInFrame (since those
functions could return such a pointer, which might become the window
function's result). That will hold still for long enough, unless
there is another window function using the same WindowObject.
I'm content to always perform a datumCopy when there's more than one
such function.
On net, these changes should provide small speed improvements as well
as removing problematic code.

The RecoveryLockLists data structure, which tracks all exclusive
locks that the startup process is holding on behalf of transactions
being replayed, did not have any provision for avoiding duplicate
entries for the same lock. Maybe that was okay when the code was
first written. However, modern practice is for checkpoints to
write fresh lists of all active exclusive locks into the WAL.
Thus, an exclusive lock that survives across multiple checkpoints
causes bloat in standbys' startup processes. If there are a lot
of such locks this can look like a memory leak, and it's even
possible to drive the startup process into a palloc failure from
an over-length List.
To fix, use a hash table instead of simple lists to track the
locks being held. Allowing for dynahash overhead, this requires
a little more space per lock than the old way (although it's the
same size as what we were allocating prior to c6e0fe1f2). It's
probably a shade slower too. However, testing indicates that the
penalty is negligible on ordinary workloads, so let's make this
change to improve robustness in extreme cases.
Patch by me, per report from Dmitriy Kuzmin. No back-patch
(for now anyway), since it seems that a significant improvement
would only occur in corner cases.

When scanning for the end of WAL, pg_resetwal has been maintaining its
own internal logic to calculate segment numbers and to parse a WAL
segment name for its timeline and segment number. The code claimed for
example that XLogFromFileName() cannot be used because it lacks the
possibility of specifying a WAL segment size, which is not the case
since fc49e24, that has made the WAL segment size configurable at
initialization time, extending this routine to do so.
Similarly, this switches one segment number calculation to use
XLByteToSeg() rather than the same logic present in xlog_internal.h.
While on it, switch to TimeLineID in pg_resetwal.c for TLI numbers
parsed from segment names, to be more consistent with

This commit expands the TAP tests of pg_upgrade when running these with
different major versions for the "old" cluster (to-be-upgraded) and the
"new" cluster (upgraded-to), by backporting some of the buildfarm

- Remove comments from the dump files, avoiding version-dependent
information.
- Remove empty lines from the dump files.
- Use --extra-float-digits=0 in the pg_dump command, when using an "old"
cluster with version equal to or lower than v11.
- Use --wal-segsize and --allow-group-access in initdb only when the
"old" cluster is equal to or higher than v11.
This allows the tests to pass down to v14 with the main regression test
suite, while v9.5~13 still generate some diffs, but these are minimal
compared to what happened before this commit. Much more could be done,
especially around dump differences with function and procedures (these
can also be avoided with direct manipulation of the dumps loaded, for
example, in a way similar to the buildfarm), but at least the basics are

Otherwise we don't use LLVM's flags when building llvmjit_wrap.cpp and
llvmjit_inline.cpp. That can cause compile time failures if the C++ compiler
doesn't default to a new enough C++ standards version and link time failures
due to ABI influencing flags like -fno-rtti.
The pre-v15 behavior was to discard all but the last result,
but with the new behavior of printing all results by default,
we will send each such result to the \g file. However,
we're still opening and closing the \g file for each result,
so you lose all but the last result anyway. Move the output-file
state up to ExecQueryAndProcessResults so that we open/close the
\g file only once per command string.
To support this without changing other behavior, we must
adjust PrintQueryResult to have separate FILE * arguments
for query and status output (since status output has never
gone to the \g file). That in turn makes it a good idea
to push the responsibility for fflush'ing output down to
PrintQueryTuples and PrintQueryStatus.
Also fix an infinite loop if COPY IN/OUT is attempted in \watch.
We used to reject that, but that error exit path got broken
somewhere along the line in v15. There seems no real reason
to reject it anyway as the code now stands, so just remove
the error exit and make sure that COPY OUT data goes to the
right place.
Also remove PrintQueryResult's unused is_watch parameter,
and make some other cosmetic cleanups (adjust obsolete
comments, break some overly-long lines).

This reverts commit db0d67db24 and
several follow-on fixes. The idea of making a cost-based choice
of the order of the sorting columns is not fundamentally unsound,
but it requires cost information and data statistics that we don't
really have. For example, relying on procost to distinguish the
relative costs of different sort comparators is pretty pointless
so long as most such comparator functions are labeled with cost 1.0.
Moreover, estimating the number of comparisons done by Quicksort
requires more than just an estimate of the number of distinct values
in the input: you also need some idea of the sizes of the larger
groups, if you want an estimate that's good to better than a factor of
three or so. That's data that's often unknown or not very reliable.
Worse, to arrive at estimates of the number of calls made to the
lower-order-column comparison functions, the code needs to make
estimates of the numbers of distinct values of multiple columns,
which are necessarily even less trustworthy than per-column stats.
Even if all the inputs are perfectly reliable, the cost algorithm
as-implemented cannot offer useful information about how to order
sorting columns beyond the point at which the average group size
is estimated to drop to 1.
Close inspection of the code added by db0d67db2 shows that there
are also multiple small bugs. These could have been fixed, but
there's not much point if we don't trust the estimates to be
accurate in-principle.
Finally, the changes in cost_sort's behavior made for very large
changes (often a factor of 2 or so) in the cost estimates for all
sorting operations, not only those for multi-column GROUP BY.
That naturally changes plan choices in many situations, and there's
precious little evidence to show that the changes are for the better.
Given the above doubts about whether the new estimates are really
trustworthy, it's hard to summon much confidence that these changes
are better on the average.
Since we're hard up against the release deadline for v15, let's
revert these changes for now. We can always try again later.
Note: in v15, I left T_PathKeyInfo in place in nodes.h even though
it's unreferenced. Removing it would be an ABI break, and it seems
a bit late in the release cycle for that.

Up to now, the ID values returned by pg_stat_get_backend_idset() and
used by pg_stat_get_backend_activity() and allied functions were just
indexes into a local array of sessions seen by the last stats refresh.
This is problematic for a few reasons. The "ID" of a session can vary
over its existence, which is surprising. Also, while these numbers
often match the "backend ID" used for purposes like temp schema
assignment, that isn't reliably true. We can fairly cheaply switch
things around to make these numbers actually be the sessions' backend
IDs. The added test case illustrates that with this definition, the
temp schema used by a given session can be obtained given its PID.

into the server (like peer, md5, scram-sha-256, gss, etc.) and
"identity" is the authentication identity as introduced by 9afffcb (peer
sets authn to the OS user name, gss to the user principal, etc.). This
format has been suggested by Tom Lane.
Note that thanks to d951052, SYSTEM_USER is available to parallel

We'd like to use precompiled headers on windows to reduce compile times. Right
now we rely on defining UMDF_USING_NTSTATUS before including postgres.h in a few
select places - which doesn't work with precompiled headers. Instead define
it globally.
When UMDF_USING_NTSTATUS is defined we need to explicitly include ntstatus.h,
winternl.h to get a comparable set of symbols. Right now these includes would
be required in a number of non-platform-specific .c files - to avoid that,
include them in win32_port.h. Based on my measurements that doesn't increase
compile times measurably.

This doesn't end up with a triple that's exactly the same as config.guess -
it'd be hard to achieve that and it doesn't seem required. We can't rely on
config.guess as we don't necessarily have a /bin/sh on windows, e.g., when
building on windows with msvc.
This isn't perfect, e.g., clang works on windows as well. But I suspect we'd
need a bunch of other changes to make clang on windows work, and we haven't
supported it historically.

Commits cf112c12 and a0dc8271 were a little too hasty in getting rid of
the pg_ prefixes where we use pread(), pwrite() and vectored variants.
We dropped support for ancient Unixes where we needed to use lseek() to
implement replacements for those, but it turns out that Windows also
changes the current position even when you pass in an offset to
ReadFile() and WriteFile() if the file handle is synchronous, despite
its documentation saying otherwise.
Switching to asynchronous file handles would fix that, but have other
complications. For now let's just put back the pg_ prefix and add some
comments to highlight the non-standard side-effect, which we can now
describe as Windows-only.

91e9e89dc modified nodeSort.c so that it used datum sorts when the
targetlist of the outer node contained only a single column. That commit
failed to recognise that the Datum returned by tuplesort_getdatum() must
be pfree'd when the type is a byref type. Ronan Dunklau did originally
propose the patch with that restriction, but that, probably through my own
fault, got lost during further development work.
Due to the timing of this report (PG15 RC1 is almost out the door), let's
just restrict the datum sort optimization to apply for byval types only.

There are still some alignment-related failures in the buildfarm,

RelFileNumbers are now assigned using a separate counter, instead of
being assigned from the OID counter. This counter never wraps around:
if all 2^56 possible RelFileNumbers are used, an internal error
occurs. As the cluster is limited to 2^64 total bytes of WAL, this
limitation should not cause a problem in practice.
If the counter were 64 bits wide rather than 56 bits wide, we would
need to increase the width of the BufferTag, which might adversely
impact buffer lookup performance. Also, this lets us use bigint for
pg_class.relfilenode and other places where these values are exposed
at the SQL level without worrying about overflow.
This should remove the need to keep "tombstone" files around until
the next checkpoint when relations are removed. We do that to keep
RelFileNumbers from being recycled, but now that won't happen
anyway. However, this patch doesn't actually change anything in
this area; it just makes it possible for a future patch to do so.

Previously, the transaction-property GUCs such as transaction_isolation
could be reset after starting a transaction, because we marked them
as GUC_NO_RESET_ALL but still allowed a targeted RESET. That leads to
assertion failures or worse, because those properties aren't supposed
to change after we've acquired a transaction snapshot.
There are some NO_RESET_ALL variables for which RESET is okay, so
we can't just redefine the semantics of that flag. Instead introduce
a separate GUC_NO_RESET flag. Mark "seed", as well as the transaction
property GUCs, as GUC_NO_RESET.
We have to disallow GUC_ACTION_SAVE as well as straight RESET, because
otherwise a function having a "SET transaction_isolation" clause can
still break things: the end-of-function restore action is equivalent
to a RESET.
No back-patch, as it's conceivable that someone is doing something
this patch will forbid (like resetting one of these GUCs at transaction
start, or "CREATE FUNCTION ... SET transaction_read_only = 1") and not
running into problems with it today. Given how long we've had this

This change simplifies some of the logic related to the generation and
creation of the backup_label and backup history files, which has become
unnecessarily complicated since the removal of the exclusive backup mode
in commit 39969e2. The code was previously generating the contents of
these files as a string (start phase for the backup_label and stop phase
for the backup history file), one problem being that the contents of the
backup_label string were scanned to grab some of its internal contents
at the stop phase.
This commit changes the logic so as we store the data required to build
these files in an intermediate structure named BackupState. The
backup_label file and backup history file strings are generated when
they are ready to be sent back to the client. Both files are now
generated with the same code path. While on it, this commit renames
some variables for clarity.
Two new files named xlogbackup.{c,h} are introduced in this commit, to
remove from xlog.c some of the logic around base backups. Note that
more could be moved to this new set of files.

Commit 25936fd46 adjusted things so that the "storeslot" we use
for remapping trigger tuples would have adequate lifespan, but it
neglected to consider the lifespan of the tuple descriptor that
the slot depends on. It turns out that in at least some cases, the
tupdesc we are passing is a refcounted tupdesc, and the refcount for
the slot's reference can get assigned to a resource owner having
different lifespan than the slot does. That leads to an error like
"tupdesc reference 0x7fdef236a1b8 is not owned by resource owner
SubTransaction". Worse, because of a second oversight in the same
commit, we'd try to free the same tupdesc refcount again while
cleaning up after that error, leading to recursive errors and an
"ERRORDATA_STACK_SIZE exceeded" PANIC.
To fix the initial problem, let's just make a non-refcounted copy
of the tupdesc we're supposed to use. That seems likely to guard
against additional problems, since there's no strong reason for
this code to assume that what it's given is a refcounted tupdesc;
in which case there's an independent hazard of the tupdesc having
shorter lifespan than the slot does. (I didn't bother trying to
free said copy, since it should go away anyway when the (sub)
transaction context is cleaned up.)
The other issue can be fixed by making the code added to
AfterTriggerFreeQuery work like the rest of that function, ie be
sure that it doesn't try to free the same slot twice in the event
of recursive error cleanup.
While here, also clean up minor stylistic issues in the test case
added by 25936fd46: don't use "create or replace function", as any
name collision within the tests is likely to have ill effects
that that won't mask; and don't use function names as generic as
trigger_function1, especially if you're not going to drop them
at the end of the test stanza.

Commit 4fb5c794e intended to add coverage of some ambuildempty

test coverage. However, by changing a temp table to unlogged
it managed to negate the intent of 4c51a2d1e, which means that
we didn't have reliable test coverage of ginvacuum.c anymore.
As things stand, much of that file might or might not get reached
depending on timing, which seems pretty undesirable.
Although this is only clearly broken for the GIN test, it seems
best to revert 4fb5c794e altogether and instead add bespoke test
cases covering unlogged indexes for these four AMs. We don't
need to do very much with them, so the extra tests are cheap.
(Note that btree, hash, and bloom already have similar test cases,
so they need no additional work.)
We can also undo dec8ad367. Since the testing deficiency that that
hacked around was later fixed by 2f2e24d90, let's intentionally leave

use the regression database for other test purposes. (The case I used
also leaves an unlogged sequence behind.)

The main parser checks whether a literal fits into an int when
deciding whether it should be put into an Integer or Float node. The
parser processes integer literals without signs. So a most-negative
integer literal will not fit into Integer and will end up as a Float
node.
The node tokenizer did this differently. It included the sign when
checking whether the literal fit into int. So a most-negative integer
would indeed fit that way and end up as an Integer node.
In order to preserve the node structure correctly, we need the node
tokenizer to also analyze integer literals without sign.
There are a number of test cases in the regression tests that have a
most-negative integer argument of some utility statement, so this

Similarly, because dropping an index does not go through

We previously thought that allowing such cases can confuse users when they
specify DROP TABLES IN SCHEMA but that doesn't seem to be the case based
on discussion. This helps to uplift the restriction during
ALTER TABLE ... SET SCHEMA which used to ensure that we couldn't end up
with a publication having both a schema and the same schema's table.
To allow this, we need to forbid having any schema on a publication if
column lists on a table are specified (and vice versa). This is because
otherwise we still need a restriction during ALTER TABLE ... SET SCHEMA to
forbid cases where it could lead to a publication having both a schema and
the same schema's table with column list.

Autoconf is showing its age, fewer and fewer contributors know how to wrangle
it. Recursive make has a lot of hard to resolve dependency issues and slow
incremental rebuilds. Our home-grown MSVC build system is hard to maintain for
developers not using Windows and runs tests serially. While these and other
issues could individually be addressed with incremental improvements, together
they seem best addressed by moving to a more modern build system.
After evaluating different build system choices, we chose to use meson, to a
good degree based on the adoption by other open source projects.
We decided that it's more realistic to commit a relatively early version of
the new build system and mature it in tree.
This commit adds an initial version of a meson based build system. It supports
building postgres on at least AIX, FreeBSD, Linux, macOS, NetBSD, OpenBSD,
Solaris and Windows (however only gcc is supported on aix, solaris). For
Windows/MSVC postgres can now be built with ninja (faster, particularly for
incremental builds) and msbuild (supporting the visual studio GUI, but
building slower).
Several aspects (e.g. Windows rc file generation, PGXS compatibility, LLVM
bitcode generation, documentation adjustments) are done in subsequent commits
requiring further review. Other aspects (e.g. not installing test-only
extensions) are not yet addressed.
When building on Windows with msbuild, builds are slower when using a visual
studio version older than 2019, because those versions do not support
MultiToolTask, required by meson for intra-target parallelism.
The plan is to remove the MSVC specific build system in src/tools/msvc soon
after reaching feature parity. However, we're not planning to remove the
autoconf/make build system in the near future. Likely we're going to keep at
least the parts required for PGXS to keep working around until all supported
versions build with meson.

Make sure that function declarations use names that exactly match the
corresponding names from function definitions for several "lexer
adjacent" backend functions.
These functions were missed by recent commits because they were obscured
by clang-tidy warnings about functions whose signature is directly under
the control of the lexer (flex seems to always generate function
declarations with unnamed parameters). We probably can't fix most of
the warnings it generates for translation units that get built from .l
and .y files, but we can at least do this much.

expression_tree_walker and allied functions have traditionally
declared their callback functions as, say, "bool (*walker) ()"
to allow for variation in the declared types of the callback
functions' context argument. This is apparently going to be
forbidden by the next version of the C standard, and the latest
version of clang warns about that. In any case it's always
been pretty poor for error-detection purposes, so fixing it is
a good thing to do.
What we want to do is change the callback argument declarations to
be like "bool (*walker) (Node *node, void *context)", which is
correct so far as expression_tree_walker and friends are concerned,
but not change the actual callback functions. Strict compliance with
the C standard would require changing them to declare their arguments
as "void *context" and then cast to the appropriate context struct
type internally. That'd be very invasive and it would also introduce
a bunch of opportunities for future bugs, since we'd no longer have
any check that the correct sort of context object is passed by outside
callers or internal recursion cases. Therefore, we're just going
to ignore the standard's position that "void *" isn't necessarily
compatible with struct pointers. No machine built in the last forty
or so years actually behaves that way, so it's not worth introducing
bug hazards for compatibility with long-dead hardware.
Therefore, to silence these compiler warnings, introduce a layer of
macro wrappers that cast the supplied function name to the official
argument type. Thanks to our use of -Wcast-function-type, this will
still produce a warning if the supplied function is seriously
incompatible with the required signature, without going as far as
the official spec restriction does.
This method fixes the problem without any need for source code changes
outside nodeFuncs.h/.c. However, it is an ABI break because the
physically called functions now have names ending in "_impl". Hence
we can only fix it this way in HEAD. In the back branches, we'll have
to settle for disabling -Wdeprecated-non-prototype.

clang 15+ will issue a set-but-not-used warning when the only
use of a variable is in autoincrements (e.g., "foo++;").
That's perfectly sensible, but it detects a few more cases that
we'd not noticed before. Silence the warnings with our usual
methods, such as PG_USED_FOR_ASSERTS_ONLY, or in one case by
actually removing a useless variable.
One thing that we can't nicely get rid of is that with %pure-parser,
Bison emits "yynerrs" as a local variable that falls foul of this
warning. To silence those, I inserted "(void) yynerrs;" in the
top-level productions of affected grammars.
Per recently-established project policy, this is a candidate
for back-patching into out-of-support branches: it suppresses
annoying compiler warnings but changes no behavior. Hence,

This is motivated by the meson patchset, which wants to put the log / data for
tests in a different place than the autoconf build. Right now log files for
tap tests have to be inside $TESTDIR/tmp_check, whereas log files for
pg_regress/isolationtester are outside of tmp_check. This change doesn't fix
the latter, but is a prerequisite.
The only test that needs adjustment is 010_tab_completion.pl, as it hardcoded
the tmp_check/ directory. Instead create a dedicated directory for the test
files. It's also a bit cleaner independently, because it doesn't intermingle
the test files with more important things like the log/ directory.

The header comment for get_cheapest_group_keys_order() claimed that the
output arguments were set to a newly allocated list which may be freed by
the calling function, however, this was not always true as the function
would simply leave these arguments untouched in some cases.
This tripped me up when working on 1349d2790 as I mistakenly assumed I
could perform a list_concat with the output parameters. That turned out
bad due to list_concat modifying the original input lists.
In passing, make it more clear that the number of distinct values is
important to reduce tiebreaks during sorts. Also, explain what the
n_preordered parameter means.
Backpatch-through: 15, where get_cheapest_group_keys_order was introduced.
If role A is a direct or indirect member of role B but does not inherit
B's privileges (because at least one relevant grant was created WITH
INHERIT FALSE) then A should not be permitted to bypass privilege
checks that require the privileges of B. For example, A can't change
the privileges of objects owned by B, nor can A drop those objects.
However, up until now, it's been possible for A to change default
privileges for role B. That doesn't seem to be correct, because a
non-inherited role grant is only supposed to permit you to assume
the identity of the granted role via SET ROLE, and should not
otherwise permit you to exercise the privileges of that role. Most
places followed that rule, but this case was an exception.
This could be construed as a security vulnerability, but it does not
seem entirely clear cut, since older branches were fuzzy about the
distinction between is_member_of_role() and has_privs_of_role() in
a number of other ways as well. Because of this, and because
user-visible behavior changes in minor releases are to be avoided
whenever possible, no back-patch.

Normally when we use object-oriented programming techniques, we
provide a pointer to an object and then some way of looking up the
associated table of callbacks, but walmethods.c/h took the alternative
approach of providing only a pointer to the table of callbacks and
thus imposed the artificial restriction that there could only ever be
one object of each type, so that the callbacks could find it via a
global variable. That doesn't seem like the right idea, so revise the
approach.
Each callback which does not already have an argument of type
Walfile * now takes a pointer to the relevant WalWriteMethod *
so that these callbacks need not rely on there being only one
object of each type.
Freeing a WalWriteMethod is now performed via a callback provided
for that purpose rather than requiring the caller to know which
WAL method they want to free.

The API contract for planstate_tree_walker() callbacks is that they
take a PlanState pointer and a context pointer. Somebody figured
they could save a couple lines of code by ignoring that, and passing
ExecShutdownNode itself as the walker even though it has but one
argument. Somewhat remarkably, we've gotten away with that so far.
However, it seems clear that the upcoming C2x standard means to
forbid such cases, and compilers that actively break such code
likely won't be far behind. So spend the extra few lines of code
to do it honestly with a separate walker function.
In HEAD, we might as well go further and remove ExecShutdownNode's
useless return value. I left that as-is in back branches though,
to forestall complaints about ABI breakage.

This makes the curent file position and pathname visible in a generic
way, so we no longer need current_walfile_name global variable or the
get_current_pos() method. Since that purported to be able to fail but
never actually did, this also lets us get rid of some unnecessary
error-handling code.
One risk of this change is that the get_current_pos() method
previously cleared the error indicator, and that will no longer happen
with the new approach. I looked for a way that this could cause problems
and did not find one.
The previous code was confused about whether "Walfile" was the
implementation-dependent structure representing a WAL file or
whether it was a pointer to that stucture. Some of the code used it
one way, and some in the other. The compiler tolerated that because
void * is interchangeable with void **, but now that Walfile is a
struct, it's necessary to be consistent. Hence, some references to
"Walfile" have been converted to "Walfile *".

In pg_receivewal, compressed output is only flushed on clean exits. The
reason to support SIGTERM as well as SIGINT (which is currently handled)
is that pg_receivewal might well be running as a daemon, and systemd's
default KillSignal is SIGTERM.
Since pg_recvlogical is also supposed to run as a daemon, teach it about
SIGTERM as well and update the documentation to match. While in there,
change pg_receivewal's time_to_stop to be sig_atomic_t like it is in
pg_recvlogical.

This appears to be a merge mistake in 96ef3237bf. We could put it
back the way it was before JSON_TABLE and it'd be two lines shorter, but
it's likely that JSON_TABLE will be back and will prefer things this

The oldest vendor-shipped Perl in the buildfarm is 5.14.2, which is
the last version that Debian Wheezy shipped. That OS is EOL, but we
keep it running because there is no other convenient way to test certain
non-mainstream 32-bit platforms. There is no bugfix in the 5.14.2 release
that is required, and yet it's also not the latest minor release --
that would be 5.14.4. To clarify the situation, we have thus arranged the
buildfarm to test 5.14.0. That allows configure scripts and documentation
to state 5.14 without fine print.
The MSVC build didn't check the version, since our previous minimum 5.8.3
was considered too old to check for on Windows. We will need a check for
Windows sometime during the v16 cycle, but that could be rendered moot
by the impending Meson conversion, so it seems safe to just document
the requirement for now.

This header is semi-private, being used only in files related to
raw parsing, so move to the backend directory where those files
live. This allows removal of Makefile rules that symlink gram.h to
src/include/parser, since gramparse.h can now include gram.h from
within the same directory. This has the side-effect of no longer
installing gram.h and gramparse.h, but there doesn't seem to be a
good reason to continue doing so.

PG_COMPRESSION_OPTION_LEVEL is removed from the compression
specification logic, and instead the compression level is always
assigned with each library's default if nothing is directly given. This
centralizes the checks on the compression methods supported by a given
build, and always assigns a default compression level when parsing a
compression specification. This results in complaining at an earlier
stage than previously if a build supports a compression method or not,
aka when parsing a specification in the backend or the frontend, and not
when processing it. zstd, lz4 and zlib are able to handle in their
respective routines setting up the compression level the case of a
default value, hence the backend or frontend code (pg_receivewal or
pg_basebackup) has now no need to know what the default compression
level should be if nothing is specified: the logic is now done so as the
specification parsing assigns it. It can also be enforced by passing
down a "level" set to the default value, that the backend will accept
(the replication protocol is for example able to handle a command like
BASE_BACKUP (COMPRESSION_DETAIL 'gzip:level=-1')).
This code simplification fixes an issue with pg_basebackup --gzip
introduced by ffd5365, where the tarball of the streamed WAL segments
would be created as of pg_wal.tar.gz with uncompressed contents, while
the intention is to compress the segments with gzip at a default level.
The origin of the confusion comes from the handling of the default
compression level of gzip (-1 or Z_DEFAULT_COMPRESSION) and the value of
0 was getting assigned, which is what walmethods.c would consider
as equivalent to no compression when streaming WAL segments with its tar
methods. Assigning always the compression level removes the confusion
of some code paths considering a value of 0 set in a specification as
either no compression or a default compression level.
Note that 010_pg_basebackup.pl has to be adjusted to skip a few tests
where the shape of the compression detail string for client and
server-side compression was checked using gzip. This is a result of the
code simplification, as gzip specifications cannot be used if a build
does not support it.

guc.c has grown to be one of our largest .c files, making it
a bottleneck for compilation. It's also acquired a bunch of
knowledge that'd be better kept elsewhere, because of our not
very good habit of putting variable-specific check hooks here.
Hence, split it up along these lines:
* guc.c itself retains just the core GUC housekeeping mechanisms.
* New file guc_funcs.c contains the SET/SHOW interfaces and some
SQL-accessible functions for GUC manipulation.
* New file guc_tables.c contains the data arrays that define the
built-in GUC variables, along with some already-exported constant
tables.
* GUC check/assign/show hook functions are moved to the variable's
home module, whenever that's clearly identifiable. A few hard-
to-classify hooks ended up in commands/variable.c, which was
already a home for miscellaneous GUC hook functions.
To avoid cluttering a lot more header files with #include "guc.h",
I also invented a new header file utils/guc_hooks.h and put all
the GUC hook functions' declarations there, regardless of their
originating module. That allowed removal of #include "guc.h"
from some existing headers. The fallout from that (hopefully
all caught here) demonstrates clearly why such inclusions are
best minimized: there are a lot of files that, for example,
were getting array.h at two or more levels of remove, despite
not having any connection at all to GUCs in themselves.
There is some very minor code beautification here, such as
renaming a couple of inconsistently-named hook functions
and improving some comments. But mostly this just moves
code from point A to point B and deals with the ensuing
needs for #include adjustments and exporting a few functions
that previously weren't exported.
Patch by me, per a suggestion from Andres Freund; thanks also
to Michael Paquier for the idea to invent guc_funcs.c.

Commit 3a0e385048 introduced a new path for unauthenticated bytes from
the client certificate to be printed unescaped to the logs. There are a
handful of these already, but it doesn't make sense to keep making the
problem worse. \x-escape any unprintable bytes.
The test case introduces a revoked UTF-8 certificate. This requires the
addition of the `-utf8` flag to `openssl req`. Since the existing
certificates all use an ASCII subset, this won't modify the existing
certificates' subjects if/when they get regenerated; this was verified
experimentally with
$ make sslfiles-clean
$ make sslfiles
Unfortunately the test can't be run in the CI yet due to a test timing
issue; see 55828a6b60.

Locale options can be specified for initdb, createdb, and CREATE
DATABASE. In initdb, it has always been possible to specify --locale
and then some --lc-* option to override a category. CREATE DATABASE
and createdb didn't allow that, requiring either the all-categories
option or only per-category options. In
f2553d4306, this was changed in CREATE
DATABASE (perhaps by accident?) to be more like the initdb behavior,
but createdb still had the old behavior.
Now we change createdb to match the behavior of CREATE DATABASE and
initdb, and also update the documentation of CREATE DATABASE to match
the new behavior, which was not done in the above commit.

The two strings are already a single palloc'd chunk, not freed; there's
no reason to allocate separate copies that have the same lifetime.
This code is only called in short-lived memory contexts (except in some
cases in TopTransactionContext, which is still short-lived enough not to
really matter), and typically only for short arrays, so the memory or
computation saved is likely negligible. However, let's fix it to avoid
leaving a bad example of code to copy. This is the only place I could
find where we're doing this with makeDefElem().

Commit d8594d123 updated the list of non-spacing codepoints used
for calculating display width, but in doing so inadvertently removed
some, since the script used for that commit only considered combining
characters.
For complete coverage for zero-width characters, include codepoints in
the category Cf (Format). To reflect the wider purpose, also rename files
and update comments that referred specifically to combining characters.
Some of these ranges have been missing since v12, but due to lack of
field complaints it was determined not important enough to justify adding
special-case logic the backbranches.

The primary fix here is to fix has_matching_range() so it does not
reference ranges->values[-1] when nranges == 0. Similar problems existed
in AssertCheckRanges() too. It does not look like any of these problems
could lead to a crash as the array in question is at the end of the Ranges
struct, and values[-1] is memory that belongs to other fields in the
struct. However, let's get rid of these rather unsafe coding practices.
In passing, I (David) adjusted some comments to try to make it more clear
what some of the fields are for in the Ranges struct. I had to study the
code to find out what nsorted was for as I couldn't tell from the
comments.

In commit f6c5edb8ab, we started to drop the replication origin slots
before tablesync worker exits to avoid consuming more slots than required.
We were dropping the replication origin in the same transaction where we
were marking the tablesync state as SYNCDONE. Now, if there is any error
after we have dropped the origin but before we commit the containing
transaction, the in-memory state of replication progress won't be rolled
back. Due to this, after the restart, tablesync worker can start streaming
from the wrong location and can apply the already processed transaction.
To fix this, we need to opportunistically drop the origin after marking
the tablesync state as SYNCDONE. Even, if the tablesync worker fails to
remove the replication origin before exit, the apply worker ensures to
clean it up afterward.

This adds additional variants of palloc, pg_malloc, etc. that
encapsulate common usage patterns and provide more type safety.
Specifically, this adds palloc_object(), palloc_array(), and
repalloc_array(), which take the type name of the object to be
allocated as its first argument and cast the return as a pointer to
that type. There are also palloc0_object() and palloc0_array()
variants for initializing with zero, and pg_malloc_*() variants of all
of the above.
Inspired by the talloc library.
