> Some Tools querying map as a struct so map.key and map.value is independent. But either way map is selected. Then MapVectorBatch is accessible,  once MapVectorBatch is accessible,
> MapVectorBatch::toString will definitely encounter segment fault due to map.key is not selected if we only select map.value.
