commit    a855118be3f0682a2061448db5a87dec50717af4
Author:   Andres Freund <andres@anarazel.de>
Date:     Wed Aug 05 11:26:01 2015 +0000
First released in: 9.6.0, 9.5.0

    Fix debug message output when connecting to a logical slot.
    
    Previously the message erroneously printed the same LSN twice as the
    assignment to the start_lsn variable was before the message. Correct
    that.
    
    Reported-By: Marko Tiikkaja

    Backpatch: 9.5, where logical decoding was introduced
