Log message:
    query_tree_mutator should copy RangeTblEntry nodes even when it's not
    planning to modify them itself.  Otherwise we end up with shared RTE
    substructure, which breaks inheritance_planner because the rte->inh
    flag needs to be independent in each copied subquery.  Per bug report
    from Chris Piker.
