Hi Ivan,

I will  try to help you with some common sense remarks because I am
Postgresql newbie, and you stated you need help quick.
If you are lucky a guru drops in.

Maybe the constraint (FK) was activated when the tables were populated
already?
Is this possible?

I do not know how to check the whole database at once.
AAFAIK it isn't possible.

But if you want to check between 2 tables if the FK works, just make a
query like:

SELECT table1_FK_Field,bla,bla FROM table1 WHERE (table1_FK_Field NOT IN
(SELECT PK_Field FROM table2))

something like that should work.

I hope you solve the problem quickly.

Good luck and regards,
Erwin
