pg_activity works localy or remotely. In a local execution context, to obtain sufficient rights to display system informations, the system user running pg_activity must be the same user running postgresql server (postgres by default), or have more rights like root. Otherwise, pg_activity can fallback to a degraded mode without displaying system informations. On the same way, postgres role used to connect to the database must be super user.
ex:

sudo -u postgres pg_activity -U postgres
