Interesting thought, though the trick would be having enough control to
be able to inject a query at the right point in the backend's
execution... maybe if there was some kind of 'debug mode' akin to gdb or
the like. Certainly seems like this could be very handy for
trouble-shooting an application you don't have the source for (or one
where the source was such spaghetti that it didn't help much).
