Rename replication_timeout to wal_sender_timeout, and add a new setting called wal_receiver_timeout that does the same at the walreceiver side. There was previously no timeout in walreceiver, so if the network went down, for example, the walreceiver could take a long time to notice that the connection was lost. Now with the two settings, both sides of a replication connection will detect a broken connection similarly. It is no longer necessary to manually set wal_receiver_status_interval to a value smaller than the timeout. Both wal sender and receiver now automatically send a "ping" message if more than 1/2 of the configured timeout has elapsed, and it hasn't received any messages from the other end.
