I'll note that 5% of your review was actually helpful (actual correction), the other 95% was needless distraction trying to enlist me in your holy crusade against the term "wraparound". It had the opposite effect. > Also, it's not clear that the term "wraparound" even describes what > happens when you corrupt the database by violating the "no more than > ~2.1 billion XIDs distance between any two unfrozen XIDs" invariant in > single-user mode. What specific thing will have wrapped around? In your first message you said "I'm hoping that I don't get too much push back on this, because it's already very difficult work." Here's some advice on how to avoid pushback: 1. Insist that all terms can only be interpreted in the most pig-headedly literal sense possible. 2. Use that premise to pretend basic facts are a complete mystery. 3. Claim that others are holding you back, and then try to move the goalposts in their work. -- John Naylor EDB: http://www.enterprisedb.com
