info:
  name: Log Checkpoints Disabled in PostgreSQL Database Instances
  author: princechaddha
  severity: medium
  description: |
    Ensure that the "log_checkpoints" database flag is enabled for your Google Cloud PostgreSQL database instances. The "log_checkpoints" flag allows checkpoints and restart points to be logged and included within the PostgreSQL server log.
  impact: |
    Without enabling "log_checkpoints", crucial log data related to checkpoints and restart points will not be captured, making it difficult to monitor and troubleshoot PostgreSQL database performance and issues.
  remediation: |
    Enable the "log_checkpoints" flag for PostgreSQL database instances to ensure logging of checkpoints and restart points for better observability.
