Help: pg_restore failure

I have a DELL server running Windows server 2003 and Postgres 8.1.

 

I used pg_dump to back up  a database test:

 

pg_dump -v -h localhost -p 5432 -U postgres -F c -b -f "D:/db_dump/backup.bak" test

 

The backup was showing the following error.

.
pg_dump: dumping contents of table history
pg_dump: [custom archiver] WARNING: ftell mismatch with expected position -- ftell used

pg_dump: dumping contents of table history_archive

pg_dump: [custom archiver] WARNING: ftell mismatch with expected position -- ftell used

pg_dump: dumping contents of table historymetadata

pg_dump: [custom archiver] WARNING: ftell mismatch with expected position -- ftell used

 

I was trying to do a Posgres 8.1.4 backup and restored it to Postgres 9.0 on a new Dell server running Windows server 2008.

 

Any clue how to resolve it?
