When you define the constraint, set it as INITIALLY
DEFERRED (or if you only sometimes want it to defer,
set it as DEFERRABLE and use SET CONSTRAINTS to change
the mode)
However, there are some problems with the deferred ri
right now if you modify the same key more than once in
a transaction -- I'm hoping to get a chance to fix
that for 7.2.  For now, you have to be careful.
