commit    bbfe3adb24c0380f5e138d97cd88dc4ac9bd1d3f
Author:   Tatsuo Ishii <ishii@sraoss.co.jp>
Date:     Sun Jul 28 02:05:51 2019 +0000

    Adjust WHERE clause of pg_stat_replication to not issue against down node.
    
    Previously the query to get replication status was unconditionally
    issued to down node, which produced annoying "no row returned" log.
