Introduce GUC_NO_RESET flag.
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
issue and not noticed, the side effects in non-assert builds can't be
too serious.

Refactor creation of backup_label and backup history files
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

more could be moved to this new set of files.

Fix tupdesc lifespan bug with AfterTriggersTableData.storeslot.
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

The main parser checks whether a literal fits into an int when

node.
The node tokenizer did this differently. It included the sign when

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.

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.

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.

Harmonize heapam and tableam parameter names.
Make sure that function declarations use names that exactly match the
corresponding names from function definitions. Having parameter names
that are reliably consistent in this way will make it easier to reason
about groups of related C functions from the same translation unit as a
module. It will also make certain refactoring tasks easier.
Like other recent commits that cleaned up function parameter names, this
commit was written with help from clang-tidy. Later commits will do the
same for other parts of the codebase.

Extend gendef.pl in preparation for meson
The main issue with using gendef.pl as-is for meson is that with meson the
filenames are a bit longer, exceeding the max commandline length when calling
dumpbin with all objects. As it's easier to pass in a library anyway, do so.
The .def file location, input and temporary file location need to be tunable
as well.

Fix misleading comment for get_cheapest_group_keys_order

would simply leave these arguments untouched in some cases.

Make ALTER DEFAULT PRIVILEGES require privileges, not membership.
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.

walmethods.c/h: Make WalWriteMethod more object-oriented.
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.

Future-proof the recursion inside ExecShutdownNode().
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.
Back-patch, with the thought that this might become of practical
importance before our stable branches are all out of service.
It doesn't seem to be fixing any live bug on any currently known
platform, however.

walmethods.c/h: Make Walfile a struct, rather than a void *
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 *".
