Perhaps you have forgotten running the contrib-module installation scripts, but you evidently did. If you are having difficulty in reloading the definitions it suggests that your new installation is lacking the contrib modules. You could install them, or manually remove the unwanted stuff from the dump file, or drop the functions from the source installation before making a dump. (Some but not all of the contrib modules have "uninstall" scripts, which would help with the last alternative.) > Anyway, my question would be: if I have postgres 8.1.x installed on > computer A and the same version of postgres installed on computer B, > which would be your recommended way of backing up data on computer A and > put it on computer B? pg_dump is certainly the preferred method. regards, tom lane
