Hi, I'm wondering ig it is possible to measure elapsed time between 2 particular queries in PostgreSQL.
what I need is the equivalent of @@TIMETICKS in Transac-SQL or CLOCK_MONOTONIC in Unix or GetTickCount in Windows These are not affected by system time changes, so time interval can be calculated even if the system time is changed by NTP or the user. That's why I can't use any function based on system time.
