Review comment:
The parent aggregate type is `NONE` by default for array type. If we
don't set the aggregate type for the children column, after deserializing in
BE, the aggregate type of the children column is `TAggregationType::type::SUM`,
because the value of `TAggregationType::type::SUM` is zero.
