Looking at walsender code,
PrimaryKeepaliveMessages
are mostly only sent withreply_requested
whenwal_sender_timeout
is non-zero. We recommendwal_sender_timeout
be set to 0. We currently only send aStandbyStatusMessage
when we see a pkm that hasreply_requested
so we almost never send them.Treat all pkms as
reply_requested
for hopefully more aggressive slot flushes.
