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.
While here, delete some dead code that guarded against getting
a NULL return from pgstat_fetch_stat_local_beentry(). That can't
happen as long as the caller is careful to pass an in-range array
index, as all the callers are. (This code may not have been dead
when written, but it surely is now.)

SYSTEM_USER is a reserved keyword of the SQL specification that,
roughly described, is aimed at reporting some information about the
system user who has connected to the database server. It may include
implementation-specific information about the means by the user
connected, like an authentication method.
This commit implements SYSTEM_USER as of auth_method:identity, where
"auth_method" is a keyword about the authentication method used to log
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
workers.

For some reason the "bpchar" type name was defined nowhere in
our SGML docs, although several places refer to it in passing.
Give it a proper mention under Character Types.
While here, also provide an explanation of how the text and varchar
types relate. The previous wording seemed to be doing its best
to sweep text under the rug, which doesn't seem very appropriate
given its prominence in other parts of the docs.

There are still some alignment-related failures in the buildfarm,
which might or might not be able to be fixed quickly, but I've also
just realized that it increased the size of many WAL records by 4 bytes
because a block reference contains a RelFileLocator. The effect of that
hasn't been studied or discussed, so revert for now.

The previous macro implementations just cast the argument to a target
type but did not check whether the input type was appropriate. The
function implementation can do better type checking of the input type.
For the *GetDatumFast() macros, converting to an inline function
doesn't work in the !USE_FLOAT8_BYVAL case, but we can use
AssertVariableIsOfTypeMacro() to get a similar level of type checking.

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

The extended query protocol implementation I added in commit
acb7e4eb6b1c 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.

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.

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
TABLES IN SCHEMA": indeed, for publications what we record is the schema
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.
There isn't resounding support for this change, but there are a few
positive votes and no opposition. Because the time to 15 RC1 is very

The bounds hardcoded in compression.c since ffd5365 (minimum at 1 and
maximum at 22) do not match the reality of what zstd is able to
handle, these values being available via ZSTD_maxCLevel() and
ZSTD_minCLevel() at run-time. The maximum of 22 is actually correct
in recent versions, but the minimum was not as the library can go down
to -131720 by design. This commit changes the code to use the run-time
values in the code instead of some hardcoded ones.
Zstd seems to assume that these bounds could change in the future, and
Postgres will be able to adapt automatically to such changes thanks to
what's being done in this commit.

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.

Before, each documentation target that built something from
postgres.sgml ran xmllint first to validate the input. Here, we
change it so that the validation only runs once and produces an output
file, and all the other targets build from that output file. This
avoids redundant work when building multiple documentation targets
(such as html and man).
Also, when we run xmllint, we can resolve entities (included files).
This helps with tools that don't support vpath builds, such as
dbtoepub.
All this also organizes the make targets a bit better for implementing
equivalent steps in meson.

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.

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.

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.

When using the BSD UUID functions, contrib/uuid-ossp expects
uuid_create() to produce a version-1 UUID. FreeBSD still does so,
but in recent NetBSD releases that function produces a version-4
(random) UUID instead. That's not acceptable for our purposes:
if the user wanted v4 she would have asked for v4, not v1.
Hence, check the version digit and complain if it's not '1'.
Also drop the documentation's claim that the NetBSD implementation
is usable. It might be, depending on which OS version you're using,
but we're not going to get into that kind of detail.
(Maybe someday we should ditch all these external libraries

Also, change the styling a bit by avoiding names in CamelCase. This is
more consistent with the style we use elsewhere.
Backpatch to 15.

Since the retirement of some older buildfarm members, the oldest Bison
that gets regular testing is 2.3. MacOS ships that version, and will
continue doing so for the forseeable future because of Apple's policy
regarding GPLv3. While Mac users could use a package manager to install
a newer version, there is no compelling reason to force them do so at
this time.

This commit raises a warning message for a combination of options
('copy_data = true' and 'origin = none') during CREATE/ALTER subscription
operations if the publication tables were also replicated from other
publishers.
During replication, we can skip the data from other origins as we have that
information in WAL but that is not possible during initial sync so we raise
a warning if there is such a possibility.
