<title>Release 13.14</title>
<formalpara>
<title>Release date:</title>
<para>2024-02-08</para>
</formalpara>
<para>
This release contains a variety of fixes from 13.13.
For information about new features in major release 13, see
<xref linkend="release-13"/>.
</para>
<sect2>
<title>Migration to Version 13.14</title>
<para>
A dump/restore is not required for those running 13.X.
</para>
<para>
However, one bug was fixed that could have resulted in corruption of
GIN indexes during concurrent updates. If you suspect such
corruption, reindex affected indexes after installing this update.
</para>
<para>
Also, if you are upgrading from a version earlier than 13.13,
see <xref linkend="release-13-13"/>.

Fix incorrect wrapping of subquery output expressions in
PlaceHolderVars (Tom Lane)
</para>
<para>
This fixes incorrect results when a subquery is underneath an outer
join and has an output column that laterally references something
outside the outer join's scope. The output column might not appear
as NULL when it should do so due to the action of the outer join.

Detect that a new catalog cache entry became stale while detoasting
its fields (Tom Lane)
</para>
<para>
We expand any out-of-line fields in a catalog tuple before inserting
it into the catalog caches. That involves database access which
might cause invalidation of catalog cache entries &mdash; but the
new entry isn't in the cache yet, so we would miss noticing that it
should get invalidated. The result is a race condition in which an
already-stale cache entry could get made, and then persist
indefinitely. This would lead to hard-to-predict misbehavior.
Fix by rechecking the tuple's visibility after detoasting.

Prevent standby servers from incorrectly processing dead index
tuples during subtransactions (Fei Changhong)
</para>
<para>
The <structfield>startedInRecovery</structfield> flag was not
correctly set for a subtransaction. This affects only processing of
dead index tuples. It could allow a query in a subtransaction to
ignore index entries that it should return (if they are already dead
on the primary server, but not dead to the standby transaction), or
to prematurely mark index entries as dead that are not yet dead on
the primary. It is not clear that the latter case has any serious
consequences, but it's not the intended behavior.

In <application>pg_dump</application>, don't dump RLS policies or

</para>
<para>
Previously, commands would be included in the dump to set these
properties, which is really incorrect since they should be
considered as internal affairs of the extension. Moreover, the
restoring user might not have adequate privilege to set them, and
indeed the dumping user might not have enough privilege to dump them
(since dumping RLS policies requires acquiring lock on their table).
