Hm, technically you might be right. Still, I like pgAdmin3 to show that
columns (when "show system objects" is enabled) for teaching purposes,
so users/newbies browsing the objects will learn "hey, there are some
reserved columns, they could have some meaning". I'd be not too excited
about emulating system column pg_attribute entries...
