There were a few typedefs that were never used to define a variable or
field. This had the effect that the buildfarm's typedefs.list would
not include them, and so they would need to be re-added manually to
keep the overall pgindent result perfectly clean.
We can easily get rid of these typedefs to avoid the issue. In a few
cases, we just let the enum or struct stand on its own without a
typedef around it. In one case, an enum was abused to define flag
bits; that's better done with macro definitions.
This fixes all the remaining issues with missing entries in the
buildfarm's typedefs.list.

This enum was used to determine the first ID to use when assigning a
custom wait event for extensions, which is always 1. It was kept so
as it would be possible to add new in-core wait events in the category
"Extension". There is no such thing currently, so let's remove this
enum until a case justifying it pops up. This makes the code simpler
and easier to understand.
This has as effect to switch back autoprewarm.c to use PG_WAIT_EXTENSION
rather than WAIT_EVENT_EXTENSION, on par with v16 and older stable
branches.

04e72ed617be pushed the skip fetch optimization (allowing bitmap heap
scans to operate like index-only scans if none of the underlying data is
needed) into heap AM implementations of bitmap table scan callbacks.
04e72ed617be added an assert that all tuples in blocks eligible for the
optimization had been NULL-filled and emitted by the end of the scan.
This assert is incorrect when not all tuples need be scanned to execute
the query; for example: a join in which not all inner tuples need to be
scanned before skipping to the next outer tuple.
Remove the assert and reset the field on which it previously asserted to
avoid incorrectly emitting NULL-filled tuples from a previous scan on
rescan.

There were three problems with the sslnegotiation options:
1. The sslmode=prefer and sslnegotiation=requiredirect combination was
somewhat dangerous, as you might unintentionally fall back to
plaintext authentication when connecting to a pre-v17 server.
2. There was an asymmetry between 'postgres' and 'direct'
options. 'postgres' meant "try only traditional negotiation", while
'direct' meant "try direct first, and fall back to traditional
negotiation if it fails". That was apparent only if you knew that the
'requiredirect' mode also exists.
3. The "require" word in 'requiredirect' suggests that it's somehow
more strict or more secure, similar to sslmode. However, I don't
consider direct SSL connections to be a security feature.
To address these problems:
- Only allow sslnegotiation='direct' if sslmode='require' or
stronger. And for the record, Jacob and Robert felt that we should do
that (or have sslnegotiation='direct' imply sslmode='require') anyway,
regardless of the first issue.
- Remove the 'direct' mode that falls back to traditional negotiation,
and rename what was called 'requiredirect' to 'direct' instead. In
other words, there is no "try both methods" option anymore, 'postgres'
now means the traditional negotiation and 'direct' means a direct SSL
connection.

Previously we searched for llvm-config-N and clang-N as well as the
unversioned names, and maintained a list of expected values of N. There
doesn't seem to be any reason to think that the default llvm-config and
clang won't be good enough, and if they aren't, they can be overridden
with LLVM_CONFIG and CLANG, so let's stop maintaining that list.
The list had not been updated since LLVM 7 with no complaints, so commit
820b5af73dc probably should have just removed it when dropping support
for 7, instead of trying to be helpful by bringing it up to date with
recent version numbers.
The Meson build system didn't have that, so no change there.

06286709e added a SERIALIZE option to EXPLAIN which included showing the
amount of kilobytes serialized. The calculation to convert bytes into
kilobytes wasn't consistent with how that's done in the rest of EXPLAIN.
Traditionally we round up to the nearest kB, but the new code rounded to
the nearest kB.
To fix this, invent a macro that does the conversion and use that macro
everywhere that requires this conversion.
Additionally, 5de890e36 added EXPLAIN (MEMORY) but included the memory
sizes in bytes. Convert these values to kilobytes to align with the
other memory related outputs.
In passing, swap out a "long" type in show_hash_info() and use a uint64
instead. We do support platforms where sizeof(Size) == 8 and
sizeof(long) == 4, so using a long there is questionable.

This README explains how to run pgindent, but it was written
for our former practice of running pgindent only infrequently.
Nowadays the plan is to keep the tree indent-clean all the time,
so the typical thing is to do an incremental pgindent run with
each commit. Revise to explain that as the normal case, and
the infrequent full-on process as a separate thing.
For now, pgperltidy is still a run-it-infrequently item.

Underscores were added to numeric literals in faff8f8e47. This change
also affected the positional parameters (e.g., $1) rule, which uses
the same production for its digits. But this did not actually work,
because the digits for parameters are processed using atol(), which
does not handle underscores and ignores whatever it cannot parse.
The underscores notation is probably not useful for positional
parameters, so for simplicity revert that rule to its old form that
only accepts digits 0-9.

Most of the infrastructure for procedure arguments was already
okay with polymorphic output arguments, but it turns out that
CallStmtResultDesc() was a few bricks shy of a load here. It thought
all it needed to do was call build_function_result_tupdesc_t, but
that function specifically disclaims responsibility for resolving
polymorphic arguments. Failing to handle that doesn't seem to be
a problem for CALL in plpgsql, but CALL from plain SQL would get
errors like "cannot display a value of type anyelement", or even
crash outright.
In v14 and later we can simply examine the exposed types of the
CallStmt.outargs nodes to get the right type OIDs. But it's a lot
more complicated to fix in v12/v13, because those versions don't
have CallStmt.outargs, nor do they do expand_function_arguments
until ExecuteCallStmt runs. We have to duplicatively run
expand_function_arguments, and then re-determine which elements
of the args list are output arguments.

Run pgindent, pgperltidy, and reformat-dat-files.
The pgindent part of this is pretty small, consisting mainly of
fixing up self-inflicted formatting damage from patches that
hadn't bothered to add their new typedefs to typedefs.list.
In order to keep it from making anything worse, I manually added
a dozen or so typedefs that appeared in the existing typedefs.list
but not in the buildfarm's list. Perhaps we should formalize that,
or better find a way to get those typedefs into the automatic list.
pgperltidy is as opinionated as always, and reformat-dat-files too.
Commit d6607016c7 moved all the jsonapi.c error messages into

json_token_error() for more clarity.
When --auth was added to initdb in commit e7029b212755 it had support
for auth options separated by space from the auth type, like:
--auth pam <servicename>
--auth ident sameuser
Passing an option to the ident auth type was removed in 01c1a12a5bb4
which left the pam auth-options support in place. 8a02339e9ba3 broke
this by inverting a calculation in the strncmp arguments, which went
unnoticed for a long time. The ability to pass options to the auth
type was never documented.
Rather than fixing the support for an undocumented feature which has
been broken for all supported versions, and which only supports one
out of many auth types which can take options, it is removed.

Presently, when this function is called for an unlogged sequence on
a standby server, it will error out with a message like
ERROR: could not open file "base/5/16388": No such file or directory
Since the pg_sequences system view uses pg_sequence_last_value(),
it can error similarly. To fix, modify the function to return NULL
for unlogged sequences on standby servers. Since this bug is
present on all versions since v15, this approach is preferable to
making the ERROR nicer because we need to repair the pg_sequences
view without modifying its definition on released versions. For
consistency, this commit also modifies the function to return NULL
for other sessions' temporary sequences. The pg_sequences view
already appropriately filters out such sequences, so there's no bug
there, but we might as well offer some defense in case someone
invokes this function directly.
Unlogged sequences were first introduced in v15, but temporary
sequences are much older, so while the fix for unlogged sequences
is only back-patched to v15, the temporary sequence portion is
back-patched to all supported versions.
We could also remove the privilege check in the pg_sequences view
definition in v18 if we modify this function to return NULL for
sequences for which the current user lacks privileges, but that is
left as a future exercise for when v18 development begins.

This test case intended to fail because setting a column as generated to
the partitioned table while leaving the partition alone is not allowed;
but instead failed because of a discrepancy of not-null constraint. Fix
this by adding the not-null constraint first, then set the column as
generated in a separate ALTER TABLE command, which gets the expected
error. Also, because the next test also wants to set the column as
not-null, add a BEGIN/ROLLBACK block so that the added not-null is
removed.

Currently, we check only owner permission for the parent table before

On other Windows build farm animals it is already skipped because they
don't use UTF-8 encoding. On "hamerkop", UTF-8 is used, and then the
test fails.
It is not clear to me (a non-Windows person looking only at buildfarm
evidence) whether Windows is less sophisticated than other OSes and
doesn't know how to downcase Turkish İ with the standard Unicode
database, or if it is more sophisticated than other systems and uses
locale-specific behavior like ICU does.
Whichever the reason, the result is the same: we need to skip the test
on Windows, just as we already do for ICU, at least until a
Windows-savvy developer comes up with a better idea. The technique for
detecting the OS is borrowed from collate.windows.win1252.sql.
This was anticipated by commit c2e8bd27, but the problem only surfaced
when Windows build farm animals started using Meson.
