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.
If max connections is 100 you get 97 concurrent connections. If all 97 are in use you then get three more concurrent connections that only accept superuser credentials.
