That gives you no gurantee it will be unique. What we are using is the following: - All tables in need of a global ID _within_ a database inherit a globid table which contains nothing but an ID of type serial. - When we need cross-database unique IDs within the same system, the globid table contains a database identifier as well (like the OID of the pg_database entry for the database).
