Hm. We don't presently have a good way to unload a library, but you can
certainly DROP EXTENSION, in which case you might expect the segment to go
away or at least be reset. But even today, once a preloaded library is
loaded, it stays loaded and its shared memory remains regardless of whether
you CREATE/DROP extension. Can you think of problems with keeping the
segment attached?
