Thanks - what about also showing the associated non-toast table ?

postgres=# \d pg_toast.pg_toast_2620
TOAST table "pg_toast.pg_toast_2620"
   Column   |  Type
------------+---------
 chunk_id   | oid
 chunk_seq  | integer
 chunk_data | bytea
FOR TABLE: "pg_catalog.pg_trigger"
Indexes:
    "pg_toast_2620_index" PRIMARY KEY, btree (chunk_id, chunk_seq)

That could be displayed differently, perhaps in the header, but I think this is
more consistent with other display.
