Does these keepalive messages are sent at the same frequency even for subscribers? Basically, I wanted to check if we have logical replication set up between 2 nodes then do we send these keep-alive messages flood? If not, then why is it different in the case of pg_recvlogical? Is it possible that the write/flush location is not updated at the pace at which we expect? Please see commit 41d5f8ad73 which seems to be talking about a similar problem. -- With Regards, Amit Kapila.
