And what if there are many more patented parts? If someone wants to have a 
patent-free variant, he has to replace big parts of postgresql? That wouldn't 
be good for postgresql. If there is a patent-problem, postgresql has to 
remove it.

What I think about is the legal implications. Sorry, but I don't know BSD very 
well. Does BSD really allow to remove this BSD-license and put his own, or 
does BSD allow to release commercial closed-source-variants under the 
BSD-license?
