This happens for me when the tables referenced in the foreign key don't exisit. Hope that helps!

Hi, I am using Postgresql 7.0.2, and have used some foreign key in my database, but I get some error like "the backend ended the connection" where I am trying to insert or delete a row to the master table(Delete cascade and update cascade). Of course, this error is no use to find the reason. So I am forced to forget foreign keys.
