It sounds to me like you are probably ignoring a lot of object-already-exists errors from pg_restore and then having it add on duplicate data to the tables. Usually people drop the database and recreate it empty before running pg_restore. There is a switch named --clean or something like that to make pg_restore emit DROP commands before recreating objects, but hardly anyone uses it because it's usually slower than dropping the whole database at once. regards, tom lane
