That's not true, there are lots of extension cords with smaller sockets for Europlugs ( http://en.wikipedia.org/wiki/Europlug http://en.wikipedia.org/wiki/Europlug ) that don't have the ground pins. However, I've never seen those on a wall socket, so I guess building codes say those must be full Schuko sockets ( http://en.wikipedia.org/wiki/Schuko http://en.wikipedia.org/wiki/Schuko ).
