A problem I see here is that "contributes or submits" is not defined. I
presume that what is probably intended is something like "submits to the
CVS repository or the patches mailing list of the PostgreSQL project".
Otherwise the term has no meaning. However, this would require some
definition of "PostgreSQL project", and IMHO any such definition would be
a Bad Thing. I suggest it is better for PostgreSQL, the software, to stand
alone as the entity distributed. The fact that a "project" exists to
maintain and develop it should not figure in the licence. Otherwise, to
pick an extreme example, suppose Oracle makes all the core developers an
offer too good to refuse, and someone else is left to pick up the pieces
and fork the project to keep it open. What rights does this forked project
have in the scheme of things? What terms apply to someone who submits
patches to this new project?

For that matter, suppose someone forks the project for other reasons; the
current licence gives anyone the right to do this at any time. With this
new suggested clause, the right to fork becomes murky. Forking is a Bad
Thing in general, but having the right to fork a project is the only
guarantee that the software will always be open.

Now one thing that might be sensible is to adopt a policy of only
accepting patches or cvs checkins that are provided irrevocably under the
terms of the PostgreSQL licence. But that is a policy for the PostgreSQL
project to adopt, not a term of the licence for redistribution of the
PostgreSQL software.
