According to what I can find on the web, Oracle treats varchar and
varchar2 as interchangeable type names, but they say they might someday
fix varchar to be spec-compliant about distinguishing null from empty
strings. (I'll believe that when I see it...)
So our examples are not wrong, but nonetheless this is a good suggestion
because changing them creates an opportunity to talk about the general
porting problem of needing to translate Oracle type names to Postgres.
I've pushed a patch based on that:

Thanks for the suggestion!
