triggered_update_columns   For triggers in the current database that specify a column list
   (like UPDATE OF column1, column2), the
   view triggered_update_columns identifies these
   columns.  Triggers that do not specify a column list are not
   included in this view.  Only those columns are shown that the
   current user owns or has some privilege other than
   SELECT on.
