In my view of the world, each of the admins would have a regular user,
with the privilege of running commands as superuser using something like
"sudo" (including running a shell).

get_home_path is psql's code.  I would expect client connections to come
from regular users, as it is considered risky to run all code with
elevated privileges, anyway.

As I recall, if you tried to start the postgres server using a superuser
account you would quickly find out that it completely refuses to start.
I suppose it works because some start script su's to the postgres
unprivileged account to run pg_ctl.  (Windows is an exception to this,
where it used to be customary to run servers using administrator
privileges, where instead of outright refusing to run, pg_ctl would drop
all privileges first.)
