> The automatic index usage does not check whether or not the indexes are still
> up-to-date when generating the index queries. This can be addressed in two
> stages, the first is to add a check before generating the index query to
> ensure that the index is still valid. The next stage may be to add some sort
> of mode where indexes are automatically updated on table writes.
