Thanks for your interest, and feedback on this patch !

Like Thomas commented down-thread my goal is to keep this contribution
as simple as possible in order to get to something that can be
committed. Improvements can follow in future CommitFests, which may end
up in the same release.
However, as stated in my original mail my goal is the simplest form of
Index Skip Scan (or whatever we call it). I welcome any help with the patch.
Best regards,
Jesper
