If you run it on the same server, with a user who has permission to access the db using ident (e.g. user "postgres"),
i.e. you have a pg_hba.conf entry like:
local  all    postgres             ident   sameuser

Then pg_dump and pg_dumpall will not require a password.

Alternatively, you can create a .pgpass file in the users home directory (if ident not available, but you *need* to think about the permissions of this file and ramifications)
