Hi,

When I implemented the replication timeout patch, I found the bug on
the HS feedback feature. When wal_receiver_status_interval is zero
and hot_standby_feedback is enabled, walreceiver sends the feedback
too aggressively. I think that the attached patch should be applied to
fix the bug.

Regards,
