If you are trying to restore forward to 9.0 you will need to use the 9.0 version
of pg_dump in either case. If you are trying to create a backup to use on the
8.1 database you might try -Fp instead of -Fc to create the dump(untested). The
bug seems to be with the binary dump version not the text version.
