No, I agree with Ian: our license says that the Postgres project does not
require a fee. It does not say that someone redistributing the material
can't charge for their efforts. It would obviously be ridiculous to
expect someone to print a multi-thousand-page book and then give it away
for free.
I do question the practicality and environmental cost of putting such
short-lived material on dead trees, though ...
