Please note that Antonin already implemented this. See his patches here: https://www.postgresql.org/message-id/77690.1725610115%40antos I proposed to leave this part out initially, which is why it hasn't been reposted. We can review and discuss after the initial patches are in. Because having an MVCC-safe mode has drawbacks, IMO we should make it optional. But you're welcome to review that part specifically if you're so inclined, and offer feedback on it. (I suggest to rewind back your checked-out tree to branch master at the time that patch was posted, for easy application. We can deal with a rebase later.) -- Álvaro Herrera 48°01'N 7°57'E — https://www.EnterpriseDB.com/ Officer Krupke, what are we to do? Gee, officer Krupke, Krup you!
