parallel queries, in single-processor enviroment?
If this client uses two connections, you can run two queries in paralell.
The client uses only 1 connection. In this

Are you sure you're not

How can I obtain the time spent by the Postgresql EXECUTOR during a given
time interval?
I am trying to get the above

Umm ... why not? If you have, say, two queries executing
