> Currently, whenever MV is created with average aggregate, a full refresh is
> done meaning it reloads the whole MV for any newly added segments. This will
> slow down the loading. With incremental data load, only the segments that are
> newly added can be loaded to the MV.
> If avg is present, rewrite the query with the sum and count of the columns to
> create MV and use them to derive avg.
