Formerly, TOAST objects were unconditionally suppressed, but since \d is able to print them it's not very clear why these variants should not. Instead, use the same rules as for system catalogs: they can be seen if you write the 'S' modifier or a table name pattern. (In practice, since hardly anybody would keep pg_toast in their search_path, it's really down to whether you use a pattern that can match pg_toast.*.) No docs change seems necessary because the docs already say that this happens for "system objects"; we're just classifying TOAST tables as being that.
