I have tried setting  idle_in_transaction_session_timeout   , however, this does not delete idle sessions.

Would there be any expiry settings to delete client idle sessions automatically ?

There is idle_session_timeout in PostgreSQL 14, but that's not much
use to you, since a) it's not out yet, and b) you're using 12.

I guess you could do something like:

SELECT pg_terminate_backend(pid) FROM pg_stat_Activity where state =
'idle' and state_change < NOW() - INTERVAL '1 hour';

Change '1 hour' to whatever you like and maybe set up a cron job to run that.

That's what we did.
