Hi, I just read about this IBM-patent-issue at www.heise.de. IBM grants this patens to all projects, which follow one of the licenses, which are approved by the open-source-initiative. And the BSD-license is as far as I see approved (I found "New BSD license").
When releasing commercial closed-source-variants of postgresql this BSD-license stays intact, so the use of these patents in postgresql seems ok.
