Log message:
    Adjust nestloop-with-inner-indexscan plan generation so that we catch
    some cases of redundant clauses that were formerly not caught.  We have
    to special-case this because the clauses involved never get attached to
    the same join restrictlist and so the existing logic does not notice
    that they are redundant.
