  name: PostgreSQL Database Instances - SQL Auditing Disabled
  author: DhiyaneshDK
  severity: high
  description: |
    SQL auditing is disabled on the PostgreSQL database instances, meaning activities such as user queries and connection events are not logged. This may hinder the ability to track database activity, detect suspicious behavior, and comply with security auditing requirements.
