Tighten security restrictions within <command>REFRESH MATERIALIZED
VIEW CONCURRENTLY</command> (Heikki Linnakangas)
</para>
<para>
One step of a concurrent refresh command was run under weak security
restrictions. If a materialized view's owner could persuade a
superuser or other high-privileged user to perform a concurrent
refresh on that view, the view's owner could control code executed
with the privileges of the user running <command>REFRESH</command>.
Fix things so that all user-determined code is run as the view's
owner, as expected.
</para>
<para>
The only known exploit for this error does not work
in <productname>PostgreSQL</productname> 16.0 and later, so it may
be that v16 is not vulnerable in practice.
</para>
<para>
The <productname>PostgreSQL</productname> Project thanks Pedro
Gallegos for reporting this problem.
