This looks to be an excellent, thorough resource on MVCC in Postgres. Here are some others:

Chapter 13 of the Postgres official docs -> https://www.postgresql.org/docs/current/static/mvcc-intro.ht...

Concurrency Deep Dive talk @ PostgresOpen 2017 -> https://www.youtube.com/watch?v=ZxhBkBNxvR0

There is a wealth of good, informative, high signal/noise ratio talks at the PostgresOpen 2017, encourage you to check it out

And another famously good resource that's not quite related:

PostgreSQL internals through pictures -> https://momjian.us/main/writings/pgsql/internalpics.pdf


This article is excellent and covers transactions/MVCC: https://brandur.org/postgres-atomicity


Thanks, noted, I'm definitely going to read that -- definitely had to widen the styles for the page though, so much wasted whitespace


This is the best FAQ I have ever read - http://www.interdb.jp/pg/faq.html


I love it. It's such a very polite way of saying, "Fuck off. I'm doing my own thing here."


Note that this is just one out of 10 chapters (translated from the author's Japanese book). Lots of other interesting technical details on other internals if you look at the table of contents.


I get "403 Forbidden"
