Cool. Sounds like we've reached a consensus, albeit with some
reservations around the fact that MINVALUE/MAXVALUE aren't actually
values, despite their names.

+/- infinity *are* values for some datatypes such as timestamps, so it
had to be something different from that, and MINVALUE/MAXVALUE are
quite short and simple, and match the syntax used by 3 other
databases.

I need to give the patch another read-through, and then I'll aim to
push it sometime in the next few days.
