Most system catalogs use OIDs as primary keys. So they cannot just

Ok, I think it is about time it is stated more clearly in the documentation.
There's no internal row id on Postgres; having one would mean more
storage requirements. If you want one, you know where to get it ... if
not, you may as well save the space.
So, how does a index relate to a row ? There have to be some way of
addressing a row ?
