RE: foreign key what???? help!!
you might want to disable the FK's before loading. This will speed up the loading, and it will not upset you with ugly error messages. After loading... enable keys.

Re: foreign key what???? help!!
Another option: make constraint DEFFERABLE and INITIALLY DEFFERED (if i spelled this correctly) In that case inforcement is done on the moment of commit. There is some limitations, however. PK must be base on a non-unique index in order to be defferable. But all FK should be fine.
