Through an unusual combination of constraints (spanning over schemas) the dump cannot be imported without errors anymore. Try using an 8.0 or 8.1 pg_dump with the 7.4 server. 7.4's pg_dump is not very bright about dumping things in the right order. If it still doesn't work with a modern pg_dump, please show details. regards, tom lane
