Well, you could switch to the user postgres (via sudo)and then
running pg_dump out of a shellscript! I do:
sudo -u postgres /usr/bin/pg_dump
having an entry like:
mirko ALL=(postgres) NOPASSWD:/usr/bin/pg_dump
in my /etc/sudoers.

See http://freshmeat.net/projects/sudo/ for more information, I guess most
Linux-distribution install sudo by default anyway.
