Cloud Config:RDS for PostgreSQL data persistence check

Last Updated:Nov 14, 2025

A resource is compliant if the `synchronous_commit` parameter is enabled. If this parameter is disabled, data may be lost if the database crashes, which puts data persistence at risk. This rule applies only to the PostgreSQL engine.

Threat level

Default threat level: Medium.

You can change the threat level as needed.

Detection logic

  • A resource is compliant if the `synchronous_commit` parameter is enabled. If this parameter is disabled, data may be lost if the database crashes, which puts data persistence at risk. This rule applies only to the PostgreSQL engine.
