    src/backend/optimizer/plan: createplan.c planner.c subselect.c

Log message:
    Cause planner to account for evaluation costs in targetlists and
    HAVING quals.  Normally this is an insignificant effect --- but it
    will not be insignificant when these clauses contain sub-selects.
    The added costs cannot affect the planning of the query containing
    them, but they might have an impact when the query is a sub-query
    of a larger one.
