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.
