What, you don't remember PostgreSQL 9.9? People were so excited for it! ;)

I seem to recall a similar thread (which I can't seem to find) about an
error, i.e. one would put in 9.1 and it would 404. Basically, we have to
deal with three difference number schemes:

- Pre-6.0
- Pre-10.0
- Post-10.0

where each of their own quirks. I think the probability of people link
hacking the release notes to the older versions is low, but even so, we
should either have, e.g. 9.1 renders the actual 9.1.0, or we should error.

I propose we do the former. Please see attached patch.

Thanks,
