37.54. 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.
