Yeah, this is what I'm doing now.  But there's a good chance that
something is going to get mapped to the OutOfStockException when it is
really a completely different kind of exception, like maybe I forgot
to set a non-null column.

So, really, I want to be able raise specific exceptions within
postgresql, and then define how those are converted to python objects.

Maybe I need to verify that postgresql supports custom exceptions.
