Ummm.... YES, there are great (potential) differences between non-Superuser and Superuser connections and their abilities. Apparently when your users were created, someone added superuser abilities to each one. That is almost certainly an error. You may have users which should have read-only ability others who should have read-write, and far fewer with superuser. Check the web pages for GRANTS as to what each user can have. If you have lots of users and don't want to assign each individually, then make a group role, give it the abilities you want, then assign your appropriate users to that group. Sounds like you need to read up on database security.

We were getting a lot of "max connections reached" errors and noticed that all our users are super users, after some digging I found the
superuser_reserved_connections parameter was not set (default to 3) this lead to some additional questions:
If all my users are superusers are they effectively limited to the number of connections defined in the
superuser_reserved_connections parameter?
Is there any significant difference between a superuser and non-superuser connection?
Any additional insight would be great.
