+        This parameter controls whether a relation referenced in a query but

+        the FROM clause. If enabled (the default), the notice
+        <literal>Adding missing FROM-clause entry for table "tablename"</literal>
+        is generated if a relation is automatically added. If not enabled,
+        an error is raised when an additional extra relation is required.
