Are you confirming then that the license of PostgreSQL doesn't permit
sublicensing, even (somehow) by implication? I might conclude from that
that the license is GPL-incompatible, which is an issue that Tom tracks
for licenses that are approved for distribution by Fedora. (Not that
that has anything to do with OSI approval.)
