No.  Consider a non-password auth mechanism, for instance SSL
certificates.  You might find that an SSL certificate file
stored where libpq will find it is already about as secure as
what you're doing now.  If you want to jump through extra
hoops for more security, I think you can use ssh-agent to
hold the keys.
