I think that compression built into the datatype and what is proposed
here are both useful and everybody's free to work on either one as the
prefer, so I don't see that as a reason not to accept this patch. And
I think this patch can be a stepping stone toward compression with an
external dictionary, so that seems like an affirmative reason to
accept this patch.

Well, I don't mind you objecting to the patch under any persona, but
so far I'm not finding your reasons convincing...
