Hmmm, if you already understand Visual Basic syntax, should we support
that too?  Or maybe we should support MySQL's use of '0000-00-00' as the
"zero" date because people "understand" that?

We're just not going to adopt a bad design because Oracle DBAs are used
to it.   If we wanted to do that, we could shut down the project and
join a proprietary DB staff.

The current discussion is:

a) Planner tweaking is sometimes necessary;
b) Oracle HINTS are a bad design for planner tweaking;
c) Can we come up with a good design for planner tweaking?

So, how about suggestions for a good design?
