Please don't top-post.
Those values are not wrong. They just don't match what our current
testing framework expects. Whether the generated plans are sensible or
not is entirely another question; the queries should still return the
same resultsets. Ordering of tuples within the resultset shouldn't
matter, but the test framework is not smart enough to compare them
that way.
