info:
  name: PostgreSQL Log Checkpoints Flag Disabled
  author: princechaddha
  severity: medium
  description: |
    Ensure that the "log_checkpoints" database flag is enabled for all PostgreSQL database instances available within your Google Cloud Platform (GCP) account. The "log_checkpoints" flag allows checkpoints and restart points to be logged in the PostgreSQL server log. By default, this flag is disabled, and enabling it ensures better tracking and debugging of database operations.
  impact: |
    Disabling the "log_checkpoints" flag may result in limited visibility into checkpoint operations, making it difficult to troubleshoot and monitor PostgreSQL database activities effectively.
  remediation: |
    Enable the "log_checkpoints" flag for all PostgreSQL database instances by updating the database configuration using the Google Cloud Console or gcloud CLI.
