commit    8a815e3fc318b441a5e8a37e4129660d81e1e012
Author:   Robert Haas <rhaas@postgresql.org>
Date:     Tue Jan 31 22:12:54 2017 +0000

    Move comment about test slightly closer to test.
    
    The addition of a TestForOldSnapshot() call here has made the
    referent of this comment slightly less clear, so move the comment
    to compensate.
    
    Amit Kapila (as part of the parallel index scan patch)
