If by this you mean that existing versions of pgAdmin II already
distributed will be relicensed, I'm not sure that action is lawful.
Generally speaking, unilaterally attempting to change an already
distributed product to another license, regardless if that license is more
or less restrictive, has little if any basis in either law or court cases.
