I've not yet looked at the latest patch, but I did put some thoughts into an email on the other thread that's been discussing UniqueKeys [1]. I'm keen to hear thoughts on the plan I mentioned over there. Likely it would be best to discuss the specifics of what additional features we need to add to UniqueKeys for skip scans over here, but discuss any chances which affect both patches over there. We certainly can't have two separate implementations of UniqueKeys, so I believe the skip scans UniqueKeys patch should most likely be based on the one in [1] or some descendant of it.
