PostgreSQL version: 9.6.9
Operating system: Core OS
Description:

Hi Team,

We are getting below error even though total connection in the database
(select count(*) from pg_stat_activity;) is not more than 10 and
max_connections are allowed 300. We are seeing below error most of the time
and only sometime it is impacting our application. Please let me know what
might be the issue?
