Wow.  Um, I can't imagine any use for that which would justify the
overhead.  And I'm practically the "settings geek".

Note that a single file can have multiple copies of the same GUC, plus
there's GUCs set interactively, as well as in the user and database
properties.  So you're looking at a lot of different "versions".

I think you're in a position of needing to interest someone else in this
issue enough to produce a patch to argue about.  I'm not seeing a lot of
interest in it here.
