I think its important to say that as soon as someone patches/forks
Postgres code then the onus is really on whoever did that to show the
problem wasn't created by them when they did that. That is very much
the reason why my company and many others don't market a forked
product and stick closely to the community distributed binaries.

I have much respect for your vendors ability to diagnose faults and
recreate them on stock Postgres if appropriate, so I think we should
wait for that to happen rather than attempt to answer this just yet.
Or alternatively, please submit a test case that fails on Postgres if
you doubt that.
