So what happens to a database that has invalid cubes in it already?
Offhand I suspect they mostly become valid since float8in will handle
NaN and the like.

Incidentally, I so wish this module were named "vector" instead of
cube. I don't think I was confused by it for ages and still find it
confuses me for a few moments before I remember what it does.
