A great summary of the issues we had with PostgreSQL -- and would pair well with a dramatic reading by @dapsays of our XID wraparound autovacuum nightmare: https://www.joyent.com/blog/manta-postmortem-7-27-2015 …https://twitter.com/rbranson/status/1246232015159975936 …
Replying to @bcantrill @dapsays
Worth noting that the situation has significantly improved since then (but there's more to do). We don't rescan parts of the table that haven't changed recently during an anti-wraparound vacuum anymore.
