If there is a way around that, I'd like to know it, even though it's not an issue now. pg_dump works OK, but of course you don't get the roles dumped. Fortunately, I kept script files that have all the database setup, so I just ran them to create all the relationships, & then used the pg_dump output. Worked flawlessly.
