    Details

      Description

      Many tpc-ds queries have predicates on date, like d_date between '1999-02-01' and (cast('1999-02-01' as date) + INTERVAL '60' day), It's very useful to find a better plan if the planner knows the max/min values of date. However, max/min in ColumnStats only support Number type currently. This issue aims to extend max/min type from Number to Comparable, and then Date, Time, Timestamp even String could be supported.
