Splendid :-) Unfortunately we will not be upgrading for some monthes still,
but anyway I'm happy.  This provides yet another good argument for upgrading
sooner.  I'm also happy to see such a perfect match:

 - A problem that can be reduced from beeing complex and
   production-specific, to simple and easily reproducible.

 - Enthusiastic people testing it and pinpointing even more precisely what
   conditions will cause the condition

 - Programmers actually fixing the issue

 - Testers verifying that it was fixed

Long live postgresql! :-)
