If you're getting a password prompt because you're trying to access another machine, you're MUCH better off using something secure like SSH with passwordless PKI authentication. That's a LOT more secure when properly set up.

If you don't think so, start going through the steps needed to protect a password stored in a file on disk...

Is this a root cron or a user cron?
What is the command which is asking for a password?

thanks achenle.
I am using the below command from a script from root cron:

/usr/PostgreSQL/8.3/bin/pg_dump -h <ip addr> -p 5432 -U postgres -F c -v -f '/apps/cmplus/backup/daily_backup/P4CMPlus_ZDC.backup' "P4CMPlus_ZDC"

then it prompts for password:
I am trying to use SSH for passwd specification as achenle mentioned. But i am able to work it out.. please let me know id tr are any ways to specify it.Smilie

Don't know. Not clear whether this is a database password or a unix user password. Manual is ambiguous but someone else might know.

PostgreSQL: Documentation: Manuals: PostgreSQL 8.3: pg_dump

Probably best to contact product support.
