The EDB Postgres Advanced Server must generate audit records when privileges/permissions are added.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity

Description
Changes in the permissions, privileges, and roles granted to users and roles must be tracked. Without an audit trail, unauthorized elevation or restriction of individuals' and groups' privileges could go undetected. Elevated privileges give users access to information and functionality that they should not have; restricted privileges wrongly deny access to authorized users. In an SQL environment, adding permissions is typically done via the GRANT command, or, in the negative, the REVOKE command.
