I can't really suggest how to recreate the dummy role, but I do have an
alternate solution.
Most probably pg_dump is complaining that role 'xxx' owns some tables. So
you can use the
attached script and add 'AND a.rolname = 'xxx' to the WHERE clause.
Then as a superuser you can use ALTER TABLE xyz OWNER TO new_owner for each
table found.
