In commit da4efa13d801ccc179f1d2c24d8a60c4a2f8ede9, sending of keepalive messages have been disabled in walsender. Commit message is " Turn off WalSender keepalives by default, users can enable if desired."
But I am not able to see how users can enable it, can you please point me if I am missing something? This doubt came as I am implementing replication timeout for walreceiver and for that walsender has to send some form of heartbeat message at predefined interval. I wanted to use keepalive to achieve the same, but then noticed the above and got stuck. With Regards, Amit Kapila.
