However, if you have ever detached a partition from a partitioned
table that has a foreign-key reference to another partitioned table,
and not dropped the former partition, then you may have catalog and/or

Ensure cached plans are marked as dependent on the calling role when
RLS applies to a non-top-level table reference (Nathan Bossart)
<ulink url="&commit_baseurl;952ff31e2">&sect;</ulink>
</para>
<para>
If a CTE, subquery, sublink, security invoker view, or coercion
projection in a query references a table with row-level security
policies, we neglected to mark the resulting plan as potentially
dependent on which role is executing it. This could lead to later
query executions in the same session using the wrong plan, and then
returning or hiding rows that should have been hidden or returned
instead.

Make <application>libpq</application> discard error messages
received during SSL or GSS protocol negotiation (Jacob Champion)
<ulink url="&commit_baseurl;7b49707b7">&sect;</ulink>
</para>
<para>
An error message received before encryption negotiation is completed
might have been injected by a man-in-the-middle, rather than being
real server output. Reporting it opens the door to various security
hazards; for example, the message might spoof a query result that a
careless user could mistake for correct output. The best answer
seems to be to discard such data and rely only
on <application>libpq</application>'s own report of the connection
failure.

Fix unintended interactions between <command>SET SESSION
AUTHORIZATION</command> and <command>SET ROLE</command> (Tom Lane)
<ulink url="&commit_baseurl;76123ded6">&sect;</ulink>
<ulink url="&commit_baseurl;dc7378793">&sect;</ulink>
</para>
<para>
The SQL standard mandates that <command>SET SESSION
AUTHORIZATION</command> have a side-effect of doing <command>SET
ROLE NONE</command>. Our implementation of that was flawed,
creating more interaction between the two settings than intended.
Notably, rolling back a transaction that had done <command>SET
SESSION AUTHORIZATION</command> would revert <literal>ROLE</literal>
to <literal>NONE</literal> even if that had not been the previous
state, so that the effective user ID might now be different from
what it had been before the transaction. Transiently
setting <varname>session_authorization</varname> in a
function <literal>SET</literal> clause had a similar effect.
A related bug was that if a parallel worker
inspected <literal>current_setting('role')</literal>, it
saw <literal>none</literal> even when it should see something else.

Prevent trusted PL/Perl code from changing environment variables

The ability to manipulate process environment variables such
as <literal>PATH</literal> gives an attacker opportunities to
execute arbitrary code. Therefore, <quote>trusted</quote> PLs must
not offer the ability to do that. To fix <literal>plperl</literal>,
replace <varname>%ENV</varname> with a tied hash that rejects any
modification attempt with a warning.
Untrusted <literal>plperlu</literal> retains the ability to change
the environment.
