Hello Adrian,
Thank you for your reply again.
I will try to use your previous suggestion that I will backup 8.1 database using 9.0 pg_dump and restore it to 9.0 database. Hopefully, 9.0 pg_dump will work on 8.1 database. I have never taken a DB course and very very new to Postgres.
Thanks again,

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.
