Verify Option with pg_dump

Hi,

recently I had problems with a corrupt pg_dump file. The problem with
the file was due to a faulty disk. The trouble with this is that I was
unaware of the disk problem and the pg_dump file corruption so I did not
have a full valid backup. In order to reduce the chances of this I was
hoping that there could be a verify option as in SQL Server for the
backups. This could be as simple as checking the CRC/MD5 as the stream
is created. So pg_dump | crc_save

The idea being that the pg_dump is crc'd before it is streamed to disk,
and then the file re-read from disk to check the CRC.

Is there a linux utility to do this or would it be simple to modify
pg_dump to do this?

Thanks

Howard.
