+      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>
+      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.
