Remove the following unused routines: - get_commit_timestamp - advance_replication_slot - monitor_replication_lag(text, boolean) - monitor_replication_lag_wait - monitor_multiple_replication_lags - wait_for_n3_sync - check_node_lag In the procedure monitor_lag_with_dblink, use the function clock_timestamp instead of now(). The now() function is stable and doesn't change the value within the monitoring loop. So, the volatile clock_timestamp looks more correct to obtain fresh value of time.
