Make sure that only the postgres user can read/write the database files.
Make sure that only the application has a password to access the database.
Make sure that there aren't any tools that let you trap
system-calls/dump memory as an unprivileged user.

You could create a ramdisk, then create the database on that. Of course,
if you lose power then you lose your data. Check the manuals for details
on "tablespaces" for how to have some DB objects in a different location.

Any reason why they shouldn't be?
Not that it matters in your case. The password might as well be
"password" - if they get access to the files/application, it's game over.
