What would you like to be able to enforce using an index that can't be solved by this patch? It only works for constraints entirely within a single table, can you think of a way to express that better? In the code/docs, mostly I call them just "index constraints" or some variation thereof. But for the lists, I think that might be too vague. I don't want to call them "don't overlap constraints", because it's not limited to a non-overlapping constraint. I also don't think "generalized unique-index constraints" is a good name: it's confusing and it makes it sound like it is some new way to use a unique index. Regards,Jeff Davis
