Is there a performance regression involved, or is it a new feature which hasn't performed well on this type of query until your patch? If the latter, I'd be inclined to give it some time on HEAD and release it in the *following* minor release unless you're *very* confident it couldn't break anything. It's an uphill battle to convince managers that it's safe to apply minor upgrades with minimal testing. It doesn't take to many slips for the boulder to roll all the way back to the bottom of that hill. -Kevin
