That's unfortunate, though I guess it makes sense. I moved the join in
the view into the SELECT clause as an EXISTS, and that seems to work
without major adverse effects. Apparently the tiny table really will be
tiny in actual use, so impact should be minimal.
I just really don't like using subselects that way. :)
Thanks, Tom!
