Agreed, and it goes beyond just columnar stores- I could see IOTs being
implemented using this notion of a different 'storage engine', but
calling it a 'storage engine' makes it sound like we want to change how
we access files and I don't think we really want to change that but
rather come up with a way to have an alternative heap..  Columnar or
IOTs would still be page-based and go through shared buffers, etc, I'd
think..
