pg_dump and password required

Hello!

I have Postgres configured so it requires password to access DB (in
pg_hba.conf).

The problem is that I want to set up an automated backup with pg_dump, but it
asks for password interactively, rather then accept password from either
command-line option or from some config-file (e.g. ~/.psqlrc)

The workaround would be to disable password requirement, but this is a
security risk I want to avoid.

Why no to add an option --password="" to command-line options of pg_dump?
