Açıklaması şöyle
Most fintech companies, who are required to log all user and application activities, set the most verbose option log_statement=all. This is the easiest way to bloat the log files and invite storage issues if storage consumption is not monitored. Pg_audit can be a smarter way of logging user activities, where you can specify which class of activities you want to log, such as READ, WRITE, DDL, or FUNCTION.

PostgreSQL 15 için açıklama şöyle
PostgreSQL supports several methods for logging server messages, including stderr (default), csvlog, and syslog. With this release, jsonlog is also supported which is convenient for exporting logs and debugging. In order to enable this, add the jsonlog under the log_destination inside the postgresql.conf file.
This will be a nice feature to have with exports to logging and monitoring tools like HoneyComb and DataDog etc.
