Password protection just doesn't play very nicely with dump scripts.
Especially not scripts you'd like to invoke from cron jobs.
I'd strongly recommend setting up a different authorization method.
One way that's reasonably secure is to run an ident server (non-broken
one of course) and enable ident authorization over local loopback only.
Then a simple "export PGHOST=127.0.0.1" frees you from entering any
more passwords.
