-- Finished a first version of the new monitoring function
- user_statistics(), which is only intended for the DBAs.
- For each database user who has logged in during the current mserver5
- session, it returns
- "username": login name of the database user,
- "querycount": the number of queries this user has executed since his/her
- first login,
- "totalticks": the total execution time (in microsecond) of the queries ran
- by this user,
- "maxquery": the query with the longest execution time (if two queries have
- the same execution time, the newer overwrites the older),
- "maxticks": the execution time of the 'maxquery' (in microsecond),
- "started": the start timestamp of the 'maxquery',
- "finished": the finish timestamp of the 'maxquery'.
