@zuyu It is expected that `statistics_` always gets initialized when a
`CatalogRelationSchema` gets constructed. Perhaps there is some change in your
branch that leaves this field uninitialized? You can add checks at different
stages (e.g. `ExecutionGenerator`, `SaveBlocksOperator::getAllWorkOrder` /
`SaveBlocksOperator::getAllWorkOrderProtos`) to see if the field is null.
