Hmm, reproduced here. There seems to be some kind of bug
in ALTER CONSTRAINT --- it looks like it's updated all the
child FKs successfully, but it actually hasn't. If you
drop the FK constraint altogether, and recreate it having
DEFERRABLE INITIALLY DEFERRED from the start, it should
work --- at least it does for me.
