I think you might be missing the point of the comments from Tom and David. To the extent that it is possible to give warnings, we already do. So this proposal just doesn't really make sense. It either warns in cases where there is no actual problem, or it gives a duplicate warning in cases where there is. Changing the details of the proposal doesn't address that fundamental problem. I would really encourage you to spend a bit more time trying to understand the current design intention and behavior before proposing changes. It actually makes a lot of sense. It is not perfect, but if there were a simple way to do better we would have likely done that a long time ago. -- Robert Haas EDB: http://www.enterprisedb.com
