I was about to say that this opens up time-to-check-time-to-use type issues. But it's the wrong thing to lock to prevent those. Having looked briefly at it, I don't understand what the locking scheme is? Shouldn't there be at least some locking against concurrent ALTERs and between ALTER and ANALYZE etc?
