But if I try to start PostgreSQL by running "sudo /etc/init.d/

With Red Hat systems, you would do chkconfig postgresql on if you
installed
the postgresql that they distribute.
On Ubuntu (and I imagine with all Debian-based systems), AFAIK you have
to manually adjust the init scripts for the runlevels that you want.
Assuming
that you want postgresql started at runlevels 3 and 5, there should be
symlinks
in /etc/rc3.d and /etc/rc5.d pointing to /etc/init.d/postgresql (so
that the boot
sequence runs /etc/init.d/postgresql start for you --- so to speak)
These symlinks should be named S??postgresql (where ?? is a two-digit
code that indicates the order in which the service is started --- maybe
99 or
some high number would be convenient, so that it is started after other
services like networking).
A ls -l /etc/rc?.d should help you visualize what you need to do. If
you're
not familiar at all with all this, do a search on runlevels and init
scripts; I'm
sure you'll find plenty of documents/tutorials out there.
Or.... The big, "brute force" hammer, would be to add a line in the
/etc/rc.local file with the very command that you're running to start it
(without sudo, of course, since that'a already being run by root)
