   ....Which makes the request effectively NULL, planning to do=20
this makes it DEFFERABLE.


Taking a different tangent ...

Is there anything in the SQL standards about NOT NULL=20
constraints being deferrable?

To my mind we should not consider implementing non-standard=20
behaviour, but if something is in the standard I can't see why=20
it shouldn't be implemented, esp. when there is no compulsion=20
for it to be used.
