The documentation for SET ROLE states that superusers who switch to a non-superuser role lose their superuser privileges. While this is true for most commands, there are exceptions such as SET ROLE and SET SESSION AUTHORIZATION, which continue to use the current session user and the authenticated user, respectively. Furthermore, the description of this command already describes its effect, so it is arguably unnecessary to include this special case. This commit removes the note about the superuser case and adds a sentence about the aforementioned exceptions to the description.
