Now now, it's only ~ 200 lines of comments.  However...

Since pg_hba.conf is re-read on every connection, I've always thought
it was pretty bogus to bulk it up with that much internal documentation.
I've not tried to measure how much time it takes the postmaster to skip
over those 200 comment lines, but it can't be completely negligible.

I'd favor reducing the in-the-file docs to about one line saying "See
such-and-such-a-place in the documentation".  Or a README.  Or
something.
