If I'm understanding you correctly, the problem is not the foreign key, it's that you marked the column NOT NULL. A foreign key constraint by itself will allow a NULL in the referencing column to pass. You choose whether you want to allow that or not by separately applying a NOT NULL constraint or not. regards, tom lane
It's marked not null as a result of being part of the primary key for that table which I can't really get around.
I can get away with not having the foreign key though, so I'll have to go down that path.
