With the right client-side code you can transmit multiple queries before
receiving the result from the first one. I don't think libpq in its
current incarnation really supports this, but in principle it's doable.
The interesting questions have to do with error handling: if the
"delayed" insert fails, what happens and what is the impact on
subsequent queries? I have no idea how MySQL defines that.
