Theoretically nothing but conceivably useful if there's an issue with recovery.
I recall various historic things weren't but should have been WAL logged.

Some of these I suggested just as a datapoint (or other brainstorms I couldn't
immediately reject). A cluster where someone has UPDATED pg_* (even
pg_statistic) or otherwise hacked on I would tend to think about differently
than a "pristine" cluster that's never seen anything more interesting than a
join.
