> * Add the ability to automatically create materialized views
>
> Right now materialized views require the user to create triggers on the
> main table to keep the summary table current. SQL syntax should be able
> to manager the triggers and summary table automatically. A more
> sophisticated implementation would automatically retrieve from the
> summary table when the main table is referenced, if possible.
