My app was running perfectly until just a few minutes ago. I keep getting this error:

FATAL: remaining connection slots are reserved for non-replication superuser connections

Currently, there are NO connections to the database. What could this problem be? I believe is an error on the Heroku side.

  • Ok, I just got an email from Heroku that they are performing maintenance on the database, so I guess that is the problem – Daniel May 20 '20 at 19:48
