-----------------------------------------+------------------------
I recently deployed an app to Heroku using Postgres free tier as
database.
I am using Django 3.2
Everything was working fine until I started getting a mail with the
following error:

{{{
Internal Server Error: /
OperationalError at /
FATAL: remaining connection slots are reserved for non-replication
superuser connections
}}}

This happens anytime I open the site. It just started doing this.
I thought waiting a while would solve the problem, but it didn't.

1. What does this error mean?
2. What causes the error?
3. How can I solve it?

My CONN_MAX_AGE is set to 500.
