    Append and SubqueryScan nodes were not passing changed-parameter signals down · 5708a567

    to their children, leading to misbehavior if they had any children that paid
    attention to chgParam (most plan node types don't).  Append's bug has been
    there a long time, but nobody had noticed because it used to be difficult
    to create a query where an Append would be used below the top level of a
    plan; so there were never any parameters getting passed down.  SubqueryScan
    is new in 7.1 ... and I'd modeled its behavior on Append :-(
