Me, too. But I don't agree with your particular choice of small
syntax adjustment. Maybe we should just let the issue drop for now.
Nobody's actually complained about this that I can recall; it's just a

inspired to think of it again because of the SQL/MED work. I'm not
sufficiently in love with this idea to walk through fire for it.
