info:
  name: Azure PostgreSQL Flexible Server log_checkpoints Disabled
  author: princechaddha
  severity: medium
  description: |
    Ensure that "log_checkpoints" server parameter is enabled for all PostgreSQL flexible database servers available within your Microsoft Azure cloud account. The "log_checkpoints" parameter allows checkpoints and restart points to be logged in the Azure PostgreSQL server log.
  impact: |
    Disabling "log_checkpoints" can prevent logging of critical events such as checkpoints and restarts, which are important for troubleshooting and ensuring the reliability of the database service.
  remediation: |
    Enable the "log_checkpoints" parameter for your Azure PostgreSQL flexible servers to ensure critical operational events are logged.
