You can use a rule to do this:

CREATE RULE cust_audit AS ON UPDATE OR DELETE TO cust DO INSERT INTO cust_hist SELECT OLD.*;

cust_hist should be identical to cust without a primary key or any 
constraints/foreign keys etc.

I'm currently working on an auditing system at present, and will be 
releasing it
soon if anyone is interested. It needs some cleaning up first, when I 
have time.
