By the way, rather than dropping the foreign key then recreating it, you
could always do this:

ALTER TABLE tablename DISABLE TRIGGER ALL;

Then it would ignore the foreign key trigger and you could put in
mischievous values... but remember to enable it again (replace DISABLE
with ENABLE).  You'll have to be a superuser to do it though.

Thom,

  Valuable information, thanks. I try to get the table structure correct
before loading it into a database. In this case I was copying structure
(with minor mods) from an existing environmental database and it took me a
while to notice the original authors used synthetic keys when they are not
needed. So, I got rid of those keys.
