   > Intervals can only be meaningfully evaluated with respect to a temporal 
type, it therefore seems surprising to me that we would be pruning on intervals 
at all, as opposed to using them in the context of range analysis for an 
arithmetic operation involving them
   
   Yes, this was surprising to us too. The issue is there is nothing that bars 
a user to have a column whose type is an interval and write an expression 
involving that. In such cases range analysis gets things wrong because of the 
order issue.
   
   > I'm not sure such a relation is possible or at least it is not trivially 
obvious to me.
   
   Agreed, definitely not trivial. We will try to iterate on this to see if we 
can arrive at a relation like that -- and if we fail we will learn something 
and we can come up with a plan B. @berkaysynnada will post an update here today 
after we think about this a little more.
