+      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.

+     <para>
+      Fix execution of hashed subplans that require cross-type comparison
+      (Tom Lane, Andreas Seltenreich)
+     </para>
+
+     <para>
+      Hashed subplans used the outer query's original comparison operator
+      to compare entries of the hash table.  This is the wrong thing if
+      that operator is cross-type, since all the hash table entries will
+      be of the subquery's output type.  For the set of hashable
+      cross-type operators in core <productname>PostgreSQL</productname>,
+      this mistake seems nearly harmless on 64-bit machines, but it can
+      result in crashes or perhaps unauthorized disclosure of server
+      memory on 32-bit machines.  Extensions might provide hashable
+      cross-type operators that create larger risks.
