I disagree with your characterization of this as a future possibility. It's a current reality, and it got to be that way by a process I describe below. > Then more companies may want to join its development.

What made PostgreSQL attractive to those companies in the first place was a known lack of need to have Extensive Conversations with Legal™ about licensing and other financial/IP matters. This in turn was guaranteed by our license, which is totally pervasive in its grants, and by our refusal, as a policy, to include anything that might compromise those pervasive grants. We have specifically excluded, and in at least one case removed, patented things in order to maintain this property. Your proposal is aimed at a problem which doesn't exist, and it is asking us to make a titanic shift in our project policy in exchange for benefits which are at best ephemeral, even according to you. Please let this go. Best, David. -- David Fetter <david(at)fetter(dot)org> http://fetter.org/ Phone: +1 415 235 3778 Remember to vote!
