Reconfigure parameters for an RDS for PostgreSQL instance

View and reconfigure parameters

Precautions

• When you reconfigure parameters on the Modifiable parameters tab, see the Value Range column corresponding to each parameter.
• After you reconfigure certain parameters, you must restart the instance for the changes to take effect. For more information, see the Force Restart column on the Modifiable parameters tab. A restart disconnects the instance. We recommend that you make appropriate service arrangements before you restart an instance. Proceed with caution.
