+Subject: [PATCH] Force certain "pljava" custom GUCs to be PGC_SUSET.
+
+Future PL/Java versions will close CVE-2016-0766 by making these GUCs
+PGC_SUSET.  This PostgreSQL change independently mitigates that PL/Java
+vulnerability, helping sites that update PostgreSQL more frequently than
+PL/Java.  Back-patch to 9.1 (all supported versions).
