\dt+ sizes don't include TOAST data

The sizes displayed by \dt+ in version 8.4.2 do not take TOAST tables
into account, presumably because the pg_relation_size does not reflect
that, either.  I think this is a bit surprising.  From a user
perspective, these are part of the table storage (I understand that
the indices might be a different story, but TOAST table are a fairly
deep implementation detail and should perhaps be hidden here).
