    make_sort_from_pathkeys()'s method for choosing which of several · 64917ccb

    equivalent sort expressions to use was broken: you can't just look
    at the relation membership, you have to actually grovel over the
    individual Vars in each expression.  I think this did work when it
    was written, but it was broken by subsequent optimizations that made
    join relations not propagate every single input variable upward.
    Must find the Var that got propagated, not choose one at random.
    Per bug report from Daniel O'Neill.
