He's talking about a SELECT rule. A SELECT rule is no more and no less than
a view - you can do nothing with select rules that you can't do with a
normal view.
(You can only have one SELECT rule, it must be named _RETURN, and it must
be a DO INSTEAD SELECT rule. If you put such a rule on a plain table, you
will find that the table changes into a view.)
