I looked briefly at GPUSort a while back. I couldn't see how to shoehorn into
POstgres the assumption that you're always sorting floating point numbers. You
would have to add some property of some data types that mapped every value to
a floating point value. I suppose we could add that as a btree proc entry for
specific data types but it would be a pretty radical change.
