Nikolay and Michael discuss logging in Postgres — mostly what to log, and why changing quite a few settings can pay off big time in the long term.
Here are some links to things they mentioned: What to log https://www.postgresql.org/docs/current/runtime-config-logging.html#RUNTIME-CONFIG-LOGGING-WHAT Our episode about Auditing https://postgres.fm/episodes/auditing Our episode on auto_explain https://postgres.fm/episodes/auto_explain
Here are the parameters they mentioned changing: log_checkpoints log_autovacuum_min_duration log_statement log_connections and log_disconnections log_lock_waits log_temp_files log_min_duration_statement log_min_duration_sample and log_statement_sample_rate
And finally, some very useful tools they meant to mention but forgot to! https://pgpedia.info https://postgresqlco.nf https://why-upgrade.depesz.com/show?from=16.9&to=17.5
