I think the major question would still remain, "What is that worth?",
if PostGreSQL says that the software works with their product. If there was a problem with it, or
if the developer decided not to upgrade to a new version with the main
product, there is still no warranty. PostGreSQL will probably not pick
up the development and upgrade it themselves.

This is very similar to asking the Linux distributions to officially support
PostGreSQL. They do to a level, but that includes just the
installation. If they upgrade and PostGreSQL in not compliant with
them anymore they will tell you they do not support it anymore. If you
think about it, PostGreSQL is a third-party product to the Operating
System. I don't think PostGreSQL is officially "REDHAT compliant" (as
an example). Then this supporting software is third-party to the DBMS. This
seems to be the way OpenSource works.

I agree with you that a third-party solution may not be the most
comfortable thing to do, but that is one of the inherent risks when
going Open Source. There is also no guarantee on PostGreSQL doing what
it is supposed to or what they say it does. The only difference
between using PostGreSQL and using a product that works with
PostGreSQL is that you have increased your risk. It was not like you
were in the safe-zone and were determining whether to take a risk or

I'm CC'ing this to the postgresql mailing list.

I fully agree to your statement (to get things "verified" and checked in as 
"supported").  Hopefully there's a way out for this...
