Hi,

If I ask detailed information about statements in log file, I got
something like:

...
2005-08-29 10:19:15 CEST ...(...)DETAIL:  ! system usage stats:
         !       101.659118 elapsed 0.640000 user 0.950000 system sec
         !       [0.670000 user 0.970000 sys total]
...

What does "elapsed" value contain exactly? Does it include
client-server communication time or just the query running time?

How can I examine what is the network overhead between the client and
the server?

Daniel
