Moreover, the term "another OSI-approved and MySQL-approved" reduces
effectively to nothing. Imagine we would change some small details in
PostgreSQL like storing the system catalog in a MySQL database. We
continue to ship PostgreSQL under BSD, but it now requires MySQL. As
long as you use PostgreSQL in a GPL conformant context, that's probably
fine, but effectively all the freedom of our BSD license is gone because
you can't do anything else with it any more.
