No, I didn't realize.  I always assumed OUT parameters were like return
values from a function ... like:

   (out1, out2, out3) = somefunction (in1, in2, in3);

I never realized you could return a SETOF those OUT parameters.  I guess
it wasn't intuitive, but I'm learning this now.

I think all the functionality I want DOES already exist.  Let me go work
with it.  Thanks.
