35.40. routine_column_usage #

   The view routine_column_usage identifies all columns that are used by a
   function or procedure, either in the SQL body or in parameter default
   expressions. (This only works for unquoted SQL bodies, not quoted
   bodies or functions in other languages.) A column is only included if
   its table is owned by a currently enabled role.
