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.
Thanks, Alvaro!
I see your point. Yes, I'll try to understand the test cases to be able to judge the results by myself. What I was worried about was some settings might break the correctness and causes unexpected problem in the product run. So I choose to first test a bit by myself instead of directly applying what I want. You know, there's a gap between developers assumptions and users intentions.
