You can configure Postgres standard logging on your server using the logging server parameters. The only way to do table-level granularity of logging in PostgreSQL is to use triggers.

The main advantage of using a proxy is moving the IO for logging out of the DB system. After the command above you get those logs in Postgres’ main log file. If you want Azure resource-level logs for operations like compute and storage scaling, see the Azure Activity Log.. Usage considerations. Logs are appended to the current file as they are emitted from Postgres. PgBadger is a PostgreSQL log analyzer with fully detailed reports and graphs. WARNING 6. Please enter a valid business email address. Reduce manual, repetitive efforts for provisioning and managing MySQL access and security with strongDM. Save the file and restart the database.
