First, when it comes to page values, perhaps we should allow pages/
blocks as a valid unit. That would allow people who want to to
specify things in pages and still be explicit about what they mean.

Second, lack of interest or no, I feel forcing specific casing/SI
units is a flat-out bad idea.

The truth is, virtually no one, even highly technical people, ever
picks nits between kB vs KiB vs KB. People will sometimes use b for
bits and B for bytes, but in the case of postgresql.conf it's very
clear that everything is talking about bytes and not bits.

Forcing people to use a specific casing scheme is just going to lead
to confusion and user frustration. If there's not a very solid
*functional* argument for it, we shouldn't do it. Wanting to enforce
a convention that people rarely use isn't a good reason.
