We certainly process multiple queries at the same time. We are not
multi-threaded in the sense we don't run multiple queries inside the
same process. Each connection gets its own process.
I am interested to hear why you thought we only do one query at a time.
Is there some information we published or someone else published that
lead you to that conclusion.
