Rolling friction on a horizontal surface

[Happiness]

Suppose a cylindrical rod is given a push such that it rolls without slipping on a horizontal plane. Am I right to say that rolling friction is only required at the start when the push is applied to initiate the rolling motion? Once the push is removed, the only forces acting on the rod are its weight and normal contact force? So the rod could continue rolling indefinitely at the same velocity ##v## and the same angular velocity ##\omega## without slipping (with ##v=r\omega##) if the plane is replaced by a frictionless one after rolling begins?

Yes, that's correct.
