Patrick,
Ok, I don't have a problem putting in the foreign key stuff, as it is
above and beyond the spec, and also something postgres supports.
Kris Jurka did most of the work on the imported/exported keys, he may
have an opinion as well?
As far as the setCatalog goes, this is probably OK too, if you get it
working, I would support it.
