That doesn't sound right to me at all. A SECURITY DEFINER function is
self contained --- if we ever failed to execute it as the owning user,
that would be a bug, and I'd be pleased to see an example.
I do recall that if you have a function that is *not* SECURITY DEFINER,
and you use it in a view, it will be invoked as the current user, not as
the view creator which is what some people expect. It's fairly easy to
get around this using SECURITY DEFINER, so it's unlikely that we'll
change it ...
