In recent versions, you should not be drop table A without specifying cascade which will drop the constraint for you (and thus you'll need to recreate it). In older versions, I'm not 100% sure what'd happen, but you probably should drop and recreate it for good measure. ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
