What to log

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!
