I'd say it is mandatory. You are opening yourself up as an easy target for
hackers if they can go directly to your database. Think about it. If any
hole in the database security is discovered, then your goose is cooked
right away. Getting the database off the web and behind a firewall should
be the least you do. That gives you two levels of protection -- the firewall
and the database.

Plus, on the postgresql side, it is much easier to have one restricted user
account from one specific machine than to try to manage thousands of
dynamically created accounts.

Just my opinion, of course.
