Tom Lane 1d2fec990c Avoid loss of code coverage with unlogged-index test cases.
Commit 4fb5c794e intended to add coverage of some ambuildempty
methods that were not getting reached, without removing any
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
an unlogged table behind to improve test coverage in the modules that
use the regression database for other test purposes.  (The case I used
also leaves an unlogged sequence behind.)

Per report from Alex Kozhemyakin.  Back-patch to v15 where the
faulty test came in.

Peter Eisentraut a6bc330192 Add read support for some missing raw parse nodes
The node types A_Const, Constraint, and A_Expr had custom output
functions, but no read functions were implemented so far.

The A_Expr output format had to be tweaked a bit to make it easier to
parse.

Be a bit more cautious about applying strncmp to unterminated strings.

Also error out if an unrecognized enum value is found in each case,
instead of just printing a placeholder value.  That was maybe ok for
debugging but won't work if we want to have robust round-tripping.

Peter Eisentraut 2cb1a5a8d4 Fix reading of BitString nodes
The node tokenizer went out of its way to store BitString node values
without the leading 'b'.  But everything else in the system stores the
leading 'b'.  This would break if a BitString node is
read-printed-read.

Also, the node tokenizer didn't know that BitString node tokens could
also start with 'x'.

Peter Eisentraut 43f4b34915 Fix reading of most-negative integer value nodes
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
issue is easily reproduced under WRITE_READ_PARSE_PLAN_TREES.

Andres Freund d811ce6ea3 pgstat: Fix transactional stats dropping for indexes
Because index creation does not go through heap_create_with_catalog() we
didn't call pgstat_create_relation(), leading to index stats of a newly
created realtion not getting dropped during rollback. To fix, move the
pgstat_create_relation() to heap_create(), which indexes do use.

Similarly, because dropping an index does not go through
heap_drop_with_catalog(), we didn't drop index stats when the transaction
dropping an index committed. Here there's no convenient common path for
indexes and relations, so index_drop() now calls pgstat_drop_relation().

Add tests for transactional index stats handling.

Remove PQsendQuery support in pipeline mode
The extended query protocol implementation I added in commit
acb7e4eb6b has bugs when used in pipeline mode.  Rather than spend
more time trying to fix it, remove that code and make the function rely
on simple query protocol only, meaning it can no longer be used in
pipeline mode.

Users can easily change their applications to use PQsendQueryParams
instead.  We leave PQsendQuery in place for Postgres 14, just in case
somebody is using it and has not hit the mentioned bugs; but we should
recommend that it not be used.

Amit Kapila 13a185f54b Allow publications with schema and table of the same schema.
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.

Based on suggestions by Peter Eisentraut.

Remove ALL keyword from TABLES IN SCHEMA for publication
This may be a bit too subtle, but removing that word from there makes
this clause no longer a perfect parallel of the GRANT variant "ALL

itself, not the tables therein, which means that any tables added to the
schema in the future are also published.  This is completely different
to what GRANT does, which is affect only the tables that exist when the
command is executed.

Andres Freund e6b6ea025c meson: ci: Convert some tasks to use meson
The Windows task is changed to use meson as there currently is no way to run
all tests in the old MSVC build system (only ninja is covered for now, we
don't have enough CI resources to test msbuild as well).

To maintain autoconf coverage, the Linux task is duplicated to test both meson
and autoconf builds (linux is currently the fastest task). FreeBSD and macOS
are also converted to meson, as it seems more important to have coverage for
meson than autoconf.

Andres Freund e6927270cd meson: Add initial version of meson based build system
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.

Some initial help for postgres developers is at
https://wiki.postgresql.org/wiki/Meson

Michael Paquier ec3c9cc202 Add definition pg_attribute_aligned() for MSVC
Visual Studio 2015+ has support for a macro to control the alignement of
structures as of __declspec(align(#)), and this commit adds a definition
of pg_attribute_aligned() based on that.  It happens that this was
already used in the implementation of atomics for MSVC.  Note that there
is still no definition fo pg_attribute_packed(), so this does not impact
itemptr.h.

Tom Lane 1c27d16e6e Revise tree-walk APIs to improve spec compliance & silence warnings.
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.

Peter Geoghegan a601366a46 Harmonize more parameter names in bulk.
Make sure that function declarations use names that exactly match the
corresponding names from function definitions in optimizer, parser,
utility, libpq, and "commands" code, as well as in remaining library
code.  Do the same for all code related to frontend programs (with the
exception of pg_dump/pg_dumpall related code).

Like other recent commits that cleaned up function parameter names, this
commit was written with help from clang-tidy.  Later commits will handle
ecpg and pg_dump/pg_dumpall.

Fix `trap` in a few shell scripts
The original `trap` lines in these scripts are incomplete: in case of
any signal, they delete the working directory but let the script run to
completion, which is useless because it will only proceed to complain
about the working directory being removed.  Add `exit` there, with the
original exit value (not rm's).

Since this is mostly just cosmetic, no backpatch.

Tom Lane 152c9f7b8f Suppress variable-set-but-not-used warnings from clang 15.
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,
back-patch to 9.5, which is as far as these patches go without
issues.  (A preliminary check shows that the prior branches
need some other set-but-not-used cleanups too, so I'll leave
them for another day.)
