Added to TODO:
* Simplify ability to create partitioned tables
This would allow creation of partitioned tables without requiring
creation of rules for INSERT/UPDATE/DELETE, and constraints for

partition selection.
* Allow auto-selection of partitioned tables for min/max() operations
I didn't add subparitions because that seems pretty complicated.
