Committed that way, along with v6-0002.

I've also done this.

That just leaves the last TODO, which is guiding users towards a
resolution. First attempt at that is attached as v7:
- v7-0001 is the same as v6-0003 with an updated commit message.
- v7-0002 is a squash! commit that prints a quick explanation and a
link to our documentation for all grease-related libpq errors.

At the moment, that link is
https://www.postgresql.org/docs/devel/libpq-connect.html#LIBPQ-CONNECT-MAX-PROTOCOL-VERSION
which will contain a <note> on grease when this is committed.

I'd still prefer that this link go to a wiki page, but in case I can't
get agreement on that, or there's some technical reason why protecting
the page wouldn't work out the way I'd hoped, or it just takes a long
time, this seems better than nothing. Switching out the URL in a later
commit shouldn't be an issue.

WDYT?
