I'd split this into two separate items now.
Fix before delete triggers on cascaded deletes to run after the cascaded
delete is done. This is odd, but seems to be what the spec requires.
Fix problems with referential action caused before triggers that modify
rows that would also be modified by the referential action. Right now,
this has a few symptoms, either you can get spurious seeming errors from
the constraint or you can end up with invalid data in the referencing
table. As far as I can see, the spec doesn't have much to say about this
because the spec doesn't seem to allow before triggers to modify tables.
