> Currently, we call {{aggCalls.get(0).`type`.getFieldList.foreach(builder.add)}} when derive row type for table aggregate. However, for types which are not composite types, the field list would be null. Table Aggregate should, of course, support non-composite types.
> To solve the problem, we should judge whether types are structured. This is because a composite type will be converted to a RelDataType which contains field list and is structured.
