If you are referring to instructions to perform cluster-wide maintenance (i.e., create data, create role) while connected to the "template1" database that it mostly a matter of convenience. template0 should not be used (if it even can be connected to) for administrative tasks because template1 has to exist and is better suited from a logical standpoint to fulfill that role. The postgres default database is also a viable candidate but often people will drop it if they feel it is not useful.
