-    The <structfield>adsrc</structfield> field is historical, and is best
-    not used, because it does not track outside changes that might affect
-    the representation of the default value.  Reverse-compiling the
-    <structfield>adbin</structfield> field (with <function>pg_get_expr</function> for
-    example) is a better way to display the default value.
