Up to now we have allowed manual creation of an ON SELECT rule on
a table to convert it into a view. That was never anything but a
horrid, error-prone hack though. pg_dump used to rely on that
behavior to deal with cases involving circular dependencies,
where a dependency loop could be broken by separating the creation
of a view from installation of its ON SELECT rule. However, we
changed pg_dump to use CREATE OR REPLACE VIEW for that in commit
d8c05aff5 (which was later back-patched as far as 9.4), so there's
not a good argument anymore for continuing to support the behavior.
The proximate reason for axing it now is that we found that the
new statistics code has failure modes associated with the relkind
change caused by this behavior. We'll patch around that in v15,
but going forward it seems like a better idea to get rid of the
need to support relkind changes.

Compression specifications are currently used by pg_basebackup and
pg_receivewal, and are able to let the user control in an extended way
the method and level of compression used. As an effect of this commit,
pg_dump's -Z/--compress is now able to use more than just an integer, as
of the grammar "method[:detail]".
The method can be either "none" or "gzip", and can optionally take a
detail string. If the detail string is only an integer, it defines the
compression level. A comma-separated list of keywords can also be used
method allows for more options, the only keyword supported now is
"level".
The change is backward-compatible, hence specifying only an integer
leads to no compression for a level of 0 and gzip compression when the
level is greater than 0.
Most of the code changes are straight-forward, as pg_dump was relying on
an integer tracking the compression level to check for gzip or no
compression. These are changed to use a compression specification and
the algorithm stored in it.
As of this change, note that the dump format is not bumped because there
is no need yet to track the compression algorithm in the TOC entries.
Hence, we still rely on the compression level to make the difference
when reading them. This will be mandatory once a new compression method
is added, though.
In order to keep the code simpler when parsing the compression
specification, the code is changed so as pg_dump now fails hard when
using gzip on -Z/--compress without its support compiled, rather than
enforcing no compression without the user knowing about it except
through a warning. Like before this commit, archive and custom formats
are compressed by default when the code is compiled with gzip, and left
uncompressed without gzip.

This commit moves the code in charge of deparsing the method and detail
strings fed later to parse_compress_specification() to a common routine,
where the backward-compatible case of only an integer being found (N
= 0 => "none", N > 1 => gzip at level N) is handled.
Note that this has a side-effect for pg_basebackup, as we now attempt to
detect "server-" and "client-" before checking for the integer-only
pre-14 grammar, where values like server-N and client-N (without the
follow-up detail string) are now valid rather than failing because of an
unsupported method name. Past grammars are still handled the same way,
but these flavors are now authorized, and would now switch to consider N
= 0 as no compression and N > 1 as gzip with the compression level used
as N, with the caller still controlling if the compression method should
be done server-side, client-side or is unspecified. The documentation
of pg_basebackup is updated to reflect that.
This benefits other code paths that would like to rely on the same logic
as pg_basebackup and pg_receivewal with option values used for
compression specifications, one area discussed lately being pg_dump.

Previously, an idle startup (recovery) process would wake up every 5
seconds to have a chance to poll for promote_trigger_file, even if that
GUC was not configured. That promotion triggering mechanism was
effectively superseded by pg_ctl promote and pg_promote() a long time
ago. There probably aren't many users left and it's very easy to change
to the modern mechanisms, so we agreed to remove the feature.
This is part of a campaign to reduce wakeups on idle systems.

pg_hba.conf and pg_ident.conf gain support for three record keywords:
- "include", to include a file.
- "include_if_exists", to include a file, ignoring it if missing.
- "include_dir", to include a directory of files. These are classified
by name (C locale, mostly) and need to be prefixed by ".conf", hence
following the same rules as GUCs.
This commit relies on the refactoring pieces done in efc9816, ad6c528,
783e8c6 and 1b73d0b, adding a small wrapper to build a list of
TokenizedAuthLines (tokenize_include_file), and the code is shaped to
offer some symmetry with what is done for GUCs with the same options.
pg_hba_file_rules and pg_ident_file_mappings gain a new field called
file_name, to track from which file a record is located, taking
advantage of the addition of rule_number in c591300 to offer an
organized view of the HBA or ident records loaded.

The lwlock wait queue scalability issue fixed in a4adc31f690 was quite hard to
find because of the exponential backoff and because we adjust spins_per_delay
over time within a backend.
To make it easier to find similar issues in the future, add a wait event for
the pg_usleep() in perform_spin_delay(). Showing a wait event while spinning
without sleeping would increase the overhead of spinlocks, which we do not
want.
We may at some later point want to have more granular wait events, but that'd
be a substantial amount of work. This provides at least some insights into
something currently hard to observe.

The postmaster normally sends SIGQUIT to force-terminate its
child processes after a child crash or immediate-stop request.
If that doesn't result in child exit within a few seconds,
we follow it up with SIGKILL. This patch provides GUC flags
that allow either of these signals to be replaced with SIGABRT.
On typically-configured Unix systems, that will result in a
core dump being produced for each such child. This can be
useful for debugging problems, although it's not something you'd
want to have on in production due to the risk of disk space
bloat from lots of core files.
The old postmaster -T switch, which sent SIGSTOP in place of
SIGQUIT, is changed to be the same as send_abort_for_crash.
As far as I can tell from the code comments, the intent of
that switch was just to block things for long enough to force
core dumps manually, which seems like an unnecessary extra step.
(Maybe at the time, there was no way to get most kernels to
produce core files with per-PID names, requiring manual core
file renaming after each one. But now it's surely the hard way.)
I also took the opportunity to remove the old postmaster -n
(skip shmem reinit) switch, which hasn't actually done anything
in decades, though the documentation still claimed it did.

Similar to how the INHERIT option controls whether or not the
permissions of the granted role are automatically available to the
grantee, the new SET permission controls whether or not the grantee
may use the SET ROLE command to assume the privileges of the granted
role.
In addition, the new SET permission controls whether or not it
is possible to transfer ownership of objects to the target role
or to create new objects owned by the target role using commands
such as CREATE DATABASE .. OWNER. We could alternatively have made
this controlled by the INHERIT option, or allow it when either
option is given. An advantage of this approach is that if you
are granted a predefined role with INHERIT TRUE, SET FALSE, you
can't go and create objects owned by that role.
The underlying theory here is that the ability to create objects
as a target role is not a privilege per se, and thus does not
depend on whether you inherit the target role's privileges. However,
it's surely something you could do anyway if you could SET ROLE
to the target role, and thus making it contingent on whether you
have that ability is reasonable.

Commit fede15417 introduced FILTER by jamming it into the existing
example introducing HAVING, which seems pedagogically poor to me;
and it added no information about what the keyword actually does.
Not to mention that the claimed output didn't match the sample
data being used in this running example.
Revert that and instead make an independent example using FILTER.
To help drive home the point that it's a per-aggregate filter,
we need to use two aggregates not just one; for consistency
expand all the examples in this segment to do that.
Also adjust the example using WHERE ... LIKE so that it'd produce
nonempty output with this sample data, and show that output.

These numbers are strictly-monotone identifiers assigned to each rule
of pg_hba_file_rules and each map of pg_ident_file_mappings when loading
the HBA and ident configuration files, indicating the order in which
they are checked at authentication time, until a match is found.
With only one file loaded currently, this is equivalent to the line
numbers assigned to the entries loaded if one wants to know their order,
but this becomes mandatory once the inclusion of external files is
added to the HBA and ident files to be able to know in which order the
rules and/or maps are applied at authentication. Note that NULL is used
when a HBA or ident entry cannot be parsed or validated, aka when an
error exists, contrary to the line number.

As of this commit, any database or user entry beginning with a slash (/)
is considered as a regular expression. This is particularly useful for
users, as now there is no clean way to match pattern on multiple HBA
lines. For example, a user name mapping with a regular expression needs
first to match with a HBA line, and we would skip the follow-up HBA
entries if the ident regexp does *not* match with what has matched in
the HBA line.
pg_hba.conf is able to handle multiple databases and roles with a
comma-separated list of these, hence individual regular expressions that
include commas need to be double-quoted.
At authentication time, user and database names are now checked in the
following order:
- Arbitrary keywords (like "all", the ones beginning by '+' for
membership check), that we know will never have a regexp. A fancy case
is for physical WAL senders, we *have* to only match "replication" for
the database.
- Regular expression matching.
- Exact match.
The previous logic did the same, but without the regexp step.
We have discussed as well the possibility to support regexp pattern
matching for host names, but these happen to lead to tricky issues based
on what I understand, particularly with host entries that have CIDRs.
This commit relies heavily on the refactoring done in a903971 and
fc579e1, so as the amount of code required to compile and execute
regular expressions is now minimal. When parsing pg_hba.conf, all the
computed regexps needs to explicitely free()'d, same as pg_ident.conf.
Documentation and TAP tests are added to cover this feature, including
cases where the regexps use commas (for clarity in the docs, coverage
for the parsing logic in the tests).
Note that this introduces a breakage with older versions, where a
database or user name beginning with a slash are treated as something to
check for an equal match. Per discussion, we have discarded this as
being much of an issue in practice as it would require a cluster to
have database and/or role names that begin with a slash, as well as HBA
entries using these. Hence, the consistency gained with regexps in
pg_ident.conf is more appealing in the long term.
**This compatibility change should be mentioned in the release notes.**

56788d215 adjusted the parallel seq scan code so that instead of handing
out a single block at a time to parallel workers, it now hands out ranges
of blocks.
Here we update the documentation which still claimed that workers received
just 1 block at a time.

Various test suites use the "openssl" program as part of their setup.
There isn't a way to override which openssl program is to be used,
other than by fiddling with the path, perhaps. This has gotten
increasingly problematic because different versions of openssl have
different capabilities and do different things by default.
This patch checks for an openssl binary in configure and meson setup,
with appropriate ways to override it. This is similar to how "lz4"
and "zstd" are handled, for example. The meson build system actually
already did this, but the result was only used in some places. This
is now applied more uniformly.

As currently designed, with a callback registered in a ERROR_CLEANUP
block, the shutdown callback would get called twice when updating
archive_library on SIGHUP, which is something that we want to avoid to
ease the life of extension writers.
Anyway, an ERROR in the archiver process is treated as a FATAL, stopping
it immediately, hence there is no need for a ERROR_CLEANUP block.
Instead of that, the shutdown callback is not called upon
before_shmem_exit(), giving to the modules the opportunity to do any
cleanup actions before the server shuts down its subsystems.
While on it, this commit adds some testing coverage for the shutdown
callback. Neither shell_archive nor basic_archive have been using it,
and one is added to shell_archive, whose trigger is checked in a TAP
test through a shutdown sequence.
