+    The SQL standard requires parentheses around the table name
+    after <literal>ONLY</literal>, as in <literal>SELECT * FROM ONLY
+    (tab1), ONLY (tab2) WHERE ...</literal>.  PostgreSQL supports that
+    as well, but the parentheses are optional.  (This point applies
+    equally to all SQL commands supporting the <literal>ONLY</literal>
+    option.)
