PostgreSQL(v9.6.5) not releasing old/inactive IDLE connections

[Md Arqum Farooqui <Md.Farooqui@xxxxxxxxxxxxx>]

Hi,

I'm facing "Too many clients already" error frequently with my PostgreSQL (v9.6.5) container (i.e. being used along with CKAN application i.e. A open source data management system ), I have observed that PostgreSQL is not releasing IDLE connections from their end. I have set "max_connetions = 100" in postgresql.

Please provide your suggestions on below queries:

1. Why PostgreSQL is not releasing IDLE connection? (If we leave the setup then postgres keep IDLE  connection even for 1 month, after that I have to restart the Postgres)
2. Is there any parameter or any solution by which i can remove unused old IDLE connection regularly?


Thanks and Regards,
Arqum farooqui
