The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/12/runtime-config-replication.html Description:
The documentation says that setting wal_receiver_status_interval to 0 disable updates of replication status completely. However walreceiver keep sending status in some cases. For example, when startup has finished processing WALs and start waiting for more: https://github.com/postgres/postgres/blob/master/src/backend/access/transam/xlog.c#L12598-L12609 It would be helpful to document in what cases status updates are still being sent.
