I find the 7.3 OID-alias types very helpful for this sort of thing:
regression=# select castsource::regtype, casttarget::regtype, castfunc::regprocedure, castcontext from pg_cast limit 1;
castsource | casttarget | castfunc | castcontext
------------+------------+--------------+-------------
bigint | smallint | int2(bigint) | a
(1 row)

There is (\dC). But it's not very bright --- I don't think you can
limit the rows displayed at all.
