Sorry, there are no deferrable check constraints in Postgres.
We only handle deferrable foreign keys (8.5 will have deferrable
unique also).  By and large there isn't any good reason that I
can see for a deferrable check constraint --- you might as well
check the row when it goes in.  (If you are trying something cute
that depends on the timing of the check, be advised that it probably
wouldn't work reliably anyway.)
