Right. There's really not much to be gained by dropping it on the
server side anyway. libpq might possibly be simplified by a useful
amount, but on the other hand we probably want to keep its current
structure for the inevitable v4 protocol.
Another area where we might think about dropping some stuff is pg_dump.
If we got rid of the requirement to support dumps from pre-7.3 servers
then it could assume server-side dependencies exist, and lose all the
code for trying to behave sanely without 'em.
