I found this issue when trying per-pg_user (role) loading of
auto_analyze and some tweaking tool. It is not necessarily set by
the user by own, but the function to decide whether to load some
module by the session-user would be usable, at least, as for me:)

It seems rather hard work if local_preload_library itself is not
removed or fixed as expressed..
