Nikolay and Michael celebrate the podcast's 1 year anniversary by going through several questions and suggestions received over the year. Here are the questions and some links to things we mentioned: Question 1: Effect of wal_log_hints=on after bulk Deletes: Why next select runs slow and generated tons of WAL? https://twitter.com/dmx551/status/1598253188926570496 wal_log_hints https://www.postgresql.org/docs/current/runtime-config-wal.html#GUC-WAL-LOG-HINTS Exploring how SELECT Queries can produce disk writes https://blog.okmeter.io/postgresql-exploring-how-select-queries-can-produce-disk-writes-f36c8bee6b6fQuestion 2: How to get started reading PostgreSQL source code. Maybe a PostgreSQL style C reference guide to consult with for non C programmers https://twitter.com/andatki/status/1578088843940593678 So, you want to be a developer? https://wiki.postgresql.org/wiki/So,_you_want_to_be_a_developer%3FGitHub search https://github.com/search?q=repo%3Apostgres%2Fpostgres+wal_log_hints&type=code The Internals of PostgreSQL (by Hironobu SUZUKI) https://www.interdb.jp/pg/ PostgreSQL 14 Internals (by Egor Rogov) https://postgrespro.com/community/books/internals Question 3: Isolation Levels Primer/Strategies — their uses in different scenarios, battle tested strategies and insights, performance tradeoffs, edge cases to consider at scale (with replication and sharding, etc.) I remember reading some interesting stuff on the jepsen analysis https://jepsen.io/analyses/postgresql-12.3 about Postgres's Serializable Isolation Level behaving more like Snapshot Isolation. Has this type of behavior or another one similar to this affected you or your clients in any significant way?Transaction Isolation https://www.postgresql.org/docs/current/transaction-iso.htmlWhat developers find surprising about Postgres transactions https://blog.lawrencejones.dev/isolation-levels/  Question 4: Data encryption in PostgresCybertec Transparent Data Encryption https://www.cybertec-postgresql.com/en/products/postgresql-transparent-data-encryption/ EDB Transparent Data Encryption https://www.enterprisedb.com/docs/tde/latest/Question 5: Migration from other DBMSsPostgreSQL transition/migration guide https://github.com/postgresql-transition-guide/guide  Question 6: Latest failover best practicesPatroni https://github.com/zalando/patroni~~~What did you like or not like?
