As long as failover_on_backend_error = on, there are number of places
where backend down is detected:

- child process attempts to connect to backend
- child process attempts to read/write from backend
- streaming replication check process attempts to connect to backend
- streaming replication check attempts to read/write from backend

Best reagards,
