commit    be5676f4143dd4f01b754ff48966011577f42bfd
Author:   Thomas Munro <tmunro@postgresql.org>
Date:     Mon Jun 24 21:17:04 2019 +0000
First released in: 12.0, 11.5

    Remove misleading comment from pathnodes.h.
    
    As of commit e5253fdc, it is no longer true that the leader always
    executes the subplan of a Gather Merge node.  Remove comment to that
    effect.
    
    Back-patch to 11.
