Hm, the "Assert(rte->subquery != NULL)" doesn't seem right ...
couldn't there be non-RTE_SUBQUERY rtes in the child?  I think the
original coding was guaranteed to visit only subquery-type RTEs
but I'm much less convinced about this one.  It might
be better to say
    if (rte->rtekind == RTE_SUBQUERY)
        IncrementVarSublevelsUp(...);

Or maybe it's okay; I'm too lazy to recheck the representation of
UNION ALL right now.
