Leopard. The change_user test failed because results of some statements depended on platform and server build flags. subselect_notembedded failure was a result of a bad merge from 5.0. Fixed the corresponding test cases.
Test case for the bug#31048 is moved to the subselect_notembedded tests as the embedded server isn't affected by this bug.
