Hi Experts,

I get the following error for python application.

django.db.utils.OperationalError: FATAL:  remaining connection slots are reserved for non-replication superuser connections

I use dj_database_url.py for configuring database.   I am using Postgres as a database

I had set connection_max_age to 0 in the config. dj_database_url.py

Still, I get this error.

I had checked the entire source code by using grep there is no connection in the source code.

I getting this error from inside docker container.  the database is outside the docker container.

the connection string I use to connect is DATABASE=postgres://test:*****@172.17.0.1/test where 172.17.0.1 is docker gateway.

max_connection =100 in postgresql.conf which located inside /etc/postgresql/9.5/main/

Any help is greatly appreciated.
