pgsql-bugs is definately not the place for this message (response to
-general).

Since I can't tell what you're precisely trying to do from the
explanation above, the easiest starting point is to look at the
documentation for triggers and then at techdocs.postgresql.org for
a couple trigger examples.

However, I don't believe you can guarantee that the foreign key trigger is
going to happen before your trigger.
