The pgcrypto docs contained a set of links for useful reading and
technical references. These sets of links were however not actively
curated and had stale content and dead links. Rather than investing
time into maintining these, this removes them altogether since there
are lots of resources online which are actively maintained.
Backpatch to all supported versions since these links have been in
the docs for a long time.

The macOS Finder application creates .DS_Store files in directories
when opened, which creates problems for serverside utilities which
expect all files to be PostgreSQL specific files. Skip these files
when encountered in pg_checksums, pg_rewind and pg_basebackup.
This was extracted from a larger patchset for skipping hidden files
and system files, where the concencus was to just skip these. Since
this is equally likely to happen in every version, backpatch to all
supported versions.

An OS crash could leave PG_VERSION empty or missing. The same symptom
appeared in a backup by block device snapshot, taken after the next
checkpoint and before the OS flushes the PG_VERSION blocks. Device
snapshots are not a documented backup method, however. Back-patch to
v15, where commit 9c08aea6a3 introduced
STRATEGY=WAL_LOG and made it the default.

We seem to have only documented a foreign key can reference the columns of
a primary key or unique constraint. Here we adjust the documentation
to mention columns in a non-partial unique index can be mentioned too.
The header comment for transformFkeyCheckAttrs() also didn't mention
unique indexes, so fix that too. In passing make that header comment
reflect reality in the various other aspects where it deviated from it.

A superuser may create a subscription with password_required=true, but
which uses a connection string without a password.
Previously, if the owner of such a subscription was changed to a
non-superuser, the non-superuser was able to utilize a password from
another source (like a password file or the PGPASSWORD environment
variable), which should not have been allowed.
This commit adds a step to re-validate the connection string before
connecting.

The note regarding character encoding form in "The Information Schema"
said that LATIN1 character repertoires only use one encoding form
LATIN1. This is not correct because LATIN1 has another encoding form
ISO-2022-JP-2. To fix this, replace LATIN1 with LATIN2, which is not
supported by ISO-2022-JP-2, thus it can be said that LATIN2 only uses
one encoding form.

The example for dropping an option was incorrectly quoting the
option key thus making it a value turning the command into an
unqualified ADD operation. The result of dropping became adding
a new key/value pair instead:
d=# alter foreign data wrapper f options (drop 'b');
ALTER FOREIGN DATA WRAPPER
d=# select fdwoptions from pg_foreign_data_wrapper where fdwname='f';
fdwoptions
------------
{drop=b}
(1 row)

The wording changed here comes from 991bfe11d2, when the only way to
trigger a promotion was with a trigger file. There are more options to
achieve this operation these days, like the SQL function pg_promote() or
the command `pg_ctl promote`, so it is confusing to assume that only a
trigger file is able to do the work.
Note also that promote_trigger_file has been removed as of cd4329d939
in 16~.

On the MERGE page, the description of the privileges required could be
taken to imply that the SELECT privilege is required on all columns of
the data source, whereas actually it is only required on the columns
referred to by conditions or expressions in the MERGE command. Re-word
it to make that a little clearer, and mention expressions as well as
conditions.
Also, add a glossary entry for MERGE, and nearby on the glossary page,
mention MERGE in the list of commands that cannot update a
materialized view.

Backpatch: 16-, where the meson build was introduced
As usual, the release notes for other branches will be made by cutting
these down, but put them up for community review first.
Also as usual for a .1 release, there are some entries here that
are not really relevant for v16 because they already appeared in 16.0.
Those'll be removed later.
This text left one with the impression that an ON SELECT rule could
be attached to a plain table, which has not been true since commit
264c06820 (meaning the text was already misleading when written,
evidently by me in 96bd67f61). However, it didn't get really bad
until b23cd185f removed the convert-a-table-to-a-view logic, which
had made it possible for scripts that thought they were attaching
ON SELECTs to tables to still work.
Rewrite into a form that makes it clear that an ON SELECT rule
is better regarded as an implementation detail of a view.
Pre-v16, point out that adding ON SELECT to a table actually
converts it to a view.
Per bug #18178 from Joshua Uyehara. Back-patch to all supported
