commit    a91bdf67c49ade2bdf6474607b64f9f0083db4a6
Author:   Magnus Hagander <magnus@hagander.net>
Date:     Sun Dec 13 15:53:38 2015 +0000
First released in: 9.6.0, 9.5.0

    Consistently set all fields in pg_stat_replication to null instead of 0
    
    Previously the "sent" field would be set to 0 and all other xlog
    pointers be set to NULL if there were no valid values (such as when
    in a backup sending walsender).
