| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | EP_OuterON constraints on the same FROM clause term) really necessary?

This is an effort to address the performance regression reported by [forum:/forumpost/96b9e5709cf47cda|forum post 96b9e5709cf47cda] that is caused by flattener restriction 29.
