Quite a few people have used OIDs up around 8000 or 9000 for this purpose;
I doubt we need a formally reserved range for it. The main problem with
doing it is the hazard that the patch'll get committed just like that,
suddenly breaking things for everyone else doing likewise.
(I would argue, in fact, that the reason we have any preassigned OIDs
above perhaps 6000 is that exactly this has happened before.)
A script such as you suggest might be a good way to reduce the temptation
to get lazy at the last minute. Now that the catalog data is pretty
machine-readable, I suspect it wouldn't be very hard --- though I'm
not volunteering either. I'm envisioning something simple like "renumber
all OIDs in range mmmm-nnnn into range xxxx-yyyy", perhaps with the
ability to skip any already-used OIDs in the target range.
