    Description

      Currently it is possible to have misaligned table/partition schemas;

      see here for example

      result of this insert statement are these null values

      This mixed partition setup can cause the stats aggregation to become quite confusing...I think it would be better to remove this thing....there is a CASCADE flag already; which changes the schema all over the table/partitions/etc.
