The previous wording had a faint archaic whiff to it, and more
importantly used "catalogs" as a verb, which while cutely
self-referential seems likely to provoke confusion in this
particular context. Also consistently use "kind" not "type" to
refer to the different kinds of relations distinguished by relkind.
Per gripe from Martin Nash. Back-patch to supported versions.

cursor_to_xmlschema() assumed that any Portal must have a tupDesc,
which is not so. Add a defensive check.
It's plausible that this mistake occurred because of the rather
poorly chosen name of the lookup function SPI_cursor_find(),
which in such cases is returning something that isn't very much
like a cursor. Add some documentation to try to forestall future
errors of the same ilk.
Report and patch by Boyu Yang (docs changes by me). Back-patch
to all supported branches.

Extend the PG_TEST_EXTRA documentation to mention resource intensive
tests as well. The previous wording only mentioned special software
and security in the main paragraph, with resource usage listed on one
of the tests in the list.
Backpatch to v15 where f47ed79cc8 added wal_consistenct_checking as
a PG_TEST_EXTRA target.

The logical_replication_mode GUC is intended for testing and debugging
purposes, but its current name may be misleading and encourage users to make
unnecessary changes.
To avoid confusion, renaming the GUC to a less misleading name
debug_logical_replication_streaming that casual users are less likely to mistakenly
assume needs to be modified in a regular logical replication setup.

The list of external language drivers and procedural languages was
never complete or exhaustive, and rather than attempting to manage
it the content has migrated to the wiki. This replaces the tables
altogether with links to the wiki as we regularly get requests for
adding various projects, which we reject without any clear policy
for why or how the content should be managed.
The threads linked to below are the most recent discussions about
this, the archives contain many more.
Backpatch to all supported branches since the list on the wiki
applies to all branches.

With the addition of INHERIT and SET options for role grants,
the historical display of role memberships in \du/\dg is woefully
inadequate. Besides those options, there are pre-existing
shortcomings that you can't see the ADMIN option nor the grantor.
To fix this, remove the "Member of" column from \du/\dg altogether
(making that output usefully narrower), and invent a new meta-command
"\drg" that is specifically for displaying role memberships. It
shows one row for each role granted to the selected role(s), with
the grant options and grantor.
We would not normally back-patch such a feature addition post
feature freeze, but in this case the change is mainly driven by
v16 changes in the server, so it seems appropriate to include it
in v16.

IN and NOT IN work fine on records and arrays, so just say that
they accept "expressions" not "scalar expressions". I think that
that phrasing was meant to say that they don't work on set-returning
expressions, but that's not the common meaning of "scalar".
Revise the description of row-constructor comparisons to make it
perhaps a bit less confusing. (This partially reverts some
dubious wording changes made by commit f56651519.)
Per gripe from Ilya Nenashev. Back-patch to supported branches.
In HEAD and v16, also drop a NOTE about pre-8.2 behavior, which
is hopefully no longer of interest to anybody.
