Review comment:
       I guess I would need qTemp, bc only having { state, sql, progress, ...q 
} = query, I cannot add extra property/ key-value-pair to it, such as 
q.sql/state/progress as object. Please let me know if my understanding is not 
correct or there is other way to do it. Thank you very much.
