Yeah. This is an important if there are any potential attackers at all,
which given today's Internet, you can be pretty sure is always the case.
A database where people are allowed to connect as superuser is a sure
way to get in trouble sooner rather than later. Having layered security
is one of the first things you should be thinking about.
FWIW I think even that one elevated user to which several people have
user/pass is a bad idea; forensics would require to know who used the
password when. It's better to have one elevated user _without login privs_,
to which people can SET ROLE when they require it. This leaves a better
trail.
If you add something like pgAudit to the mix and direct its logs (or all
Postgres logs) to a remote server where they can't easily be tampered
with by attackers, you'll have a better trail of who did what, when,
with what credentials.
