What is measured by the \timing option? The figures reported
are slightly larger than those loged when the log_duration parameter
is true.
=> select count(*) from foo;
count
--------
362921
(1 row)
Time: 5500.88 ms
while in syslog, the timing was "LOG: duration: 5.499783 sec". There
is a difference of 1.097 ms.
In both cases what is this duration? Real time or CPU time?
