I know the fee clause from licenses such as Zero-Clause BSD, ISC License, and GPLv3. They state "with or without fee" or "gratis or for a fee" pertaining to the distribution. That's also how I interpret the fee clause in the PostgreSQL license with the difference that it does not permit taking a fee. > AFAIR the documentation has previously been published in book form, though as > it runs to about 3,000 A4 pages now, the logistics are non-trivial. It's also out of date pretty quickly with four releases a year. -- Erik
