That seems a little bizarre.  Wouldn't we want to have a switch that
just flips the SELECT output format from one style to the other?

This is also a good time to stop and ask whether the frontend/backend
protocol needs to change to support this.  Not having read the spec,
I have no idea what the low-level transport needs are for XML output,
but I suspect our present protocol is not it ...
