Depends what you consider "user created". System catalogs with
manually-assigned OIDs will have OIDs below 10K, but initdb creates
numerous things that don't have manually-assigned OIDs. And what of,
say, TOAST tables attached to user tables?
You might find the comments for FirstNormalObjectId in
src/include/access/transam.h enlightening.
I think the better question is "Why do you want to know this?" I suspect
there's a better way to do whatever you're trying to do.
