I think dates could be added to that list as well. But any 
implementation that doesn't do ranges of timestamptz are non-starters as 
far as I'm concerned. Certainly int64 timestamps and numeric are doable. 
And Jeff's period implementation supports float timestamps. I never use 
float timestamps so I can only assume that he made it work.

Personally, I'd rather just see float timestamps go away. And if the 
range types never supported float or float timestamps, I'd be ok with that.
