How would the optimizer know that the maximum value is in that specific partition? There is neither a global index for a partitioned table nor an optimizer artifact to know aggregate information before scanning all of the partitions. Maybe when we have a better support for table partitioning such optimizer artifact would be implemented but don't hold your breath.
