> If someone runs "compute stats" on the underlying tables for a query, the
> tuple cache key should only change if the plan actually changes. The resource
> estimates should not be incorporated into the tuple cache key as they have no
> semantic impact. The code already excludes the resource estimates from the
> key for the PlanNode, but we should have tests for computing stats and
> verifying that the key doesn't change.
