Please stop all this discussion of patents in this area.  Bringing up a 
US patents here makes US list members more likely to be treated as 
willful infringers of that patent: 
http://www.ipwatchdog.com/patent/advanced-patent/willful-patent-infringement/ 
if the PostgreSQL code duplicates that method one day.

The idea of surveying patents in some area so that their methods can be 
avoided in code you develop, that is a reasonable private stance to 
take.  But don't do that on the lists.
