Enabling SQL Audit

Scenarios

After SQL audit is enabled for RDS for PostgreSQL DB instances, the system records SQL operations and uploads logs every half an hour or when the size of a single record reaches 100 MB. The generated audit logs are stored in OBS.

Precautions

• SQL audit is disabled for DB instances by default because enabling it increases database loads.
• To enable SQL audit, you need to install the pgAudit extension first. For details, see pgAudit.
