func ObserveQueryTime(query, subquery string, start time.Time)

monitoring.ObserveQueryTime computes the time elapsed since `start` to represent the query time. 1. `query` is a pgSession function name. 2. `subquery` is a specific query or a batched query. 3. `start` is the time right before query is executed.
