pg_walsummary: Improve stability of test checking statistics
Per buildfarm member culicidae, the query checking for stats reported by
the WAL summarizer related to WAL reads is proving to be unstable.

aio: Combine io_uring memory mappings, if supported
By default io_uring creates a shared memory mapping for each io_uring
instance, leading to a large number of memory mappings. Unfortunately a large
number of memory mappings slows things down, backend exit is particularly
affected. To address th

Consider explicit incremental sort for Append and MergeAppend
For an ordered Append or MergeAppend, we need to inject an explicit
sort into any subpath that is not already well enough ordered.
Currently, only explicit full sorts are considered; incremental sorts
are not yet taken into account.

oauth: Fix kqueue detection on OpenBSD
In b0635bfda, I added an early header check to the Meson OAuth support,
which was intended to duplicate the later checks for
HAVE_SYS_[EVENT|EPOLL]_H. However, I implemented the new test via
check_header() -- which tries to compile -- rather than has_header()

Adapt pg_upgrade test to pg_lsn output format difference
Commit 2633dae2e487 added some zero padding to various LSNs output
routines so that the low word is always 8 hex digits long, for easy
human consumption. This included the pg_lsn datatype, which breaks the
pg_upgrade test when it compares t
Restore the ability to run pl/pgsql expression queries in parallel.
pl/pgsql's notion of an "expression" is very broad, encompassing
any SQL SELECT query that returns a single column and no more than
one row. So there are cases, for example evaluation of an aggregate
function, where the query inv

Refactor some repetitive SLRU code
Functions to bootstrap and zero pages in various SLRU callers were
fairly duplicative. We can slash almost two hundred lines with a couple
of simple helpers:

Standardize LSN formatting by zero padding
This commit standardizes the output format for LSNs to ensure consistent
representation across various tools and messages. Previously, LSNs were
inconsistently printed as `%X/%X` in some contexts, while others used
zero-padding. This often led to confus
