routine_sequence_usage
   The view routine_sequence_usage identifies all sequences
   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 sequence is only
   included if that sequence is owned by a currently enabled role.
