Group -
The EDB Postgres Advanced Server must allow only the ISSM (or individuals or roles appointed by the ISSM) to select which auditable events are to be audited.

SRG-APP-000101-DB-000044
Group -
The EDB Postgres Advanced Server must include additional, more detailed, organization-defined information in the audit records for audit events identified by type, location, or subject.
