+ Require schema qualification to cast to a temporary type when using
+ functional cast syntax (Noah Misch)
+ </para>
+
+ <para>
+ We have long required invocations of temporary functions to
+ explicitly specify the temporary schema, that
+ is <literal>pg_temp.<replaceable>func_name</replaceable>(<replaceable>args</replaceable>)</literal>.
+ Require this as well for casting to temporary types using functional
+ notation, for
+ example <literal>pg_temp.<replaceable>type_name</replaceable>(<replaceable>arg</replaceable>)</literal>.
+ Otherwise it's possible to capture a function call using a temporary
+ object, allowing privilege escalation in much the same ways that we
+ blocked in CVE-2007-2138.
