... RETURNING ctid

This might be a little tricky; you'd have to be sure the RETURNING
code executes late enough that a TID has been assigned to the tuple.
Not sure if post-insert trigger time is late enough or not (Jan?)
but in principle it's not a special case at all, just a system
attribute the same as OID.
