Deleting a DB Instance or Read Replica

Scenarios

To release resources, you can delete DB instances or read replicas as required on the Instances page.

Constraints

• DB instances cannot be deleted when operations are being performed on them. They can be deleted only after the operations are complete.
• If a backup of a DB instance is being restored, the instance cannot be deleted.
• A stopped instance cannot be deleted through the console.
• If you delete a DB instance, its automated backups will also be deleted and you will no longer be billed for them. Manual backups, however, will be retained and generate additional costs.

• If you delete a primary DB instance, its standby DB instance and read replicas (if any) are also deleted automatically. Exercise caution when performing this operation.
• You will not be billed for the instances that were not successfully created.
• Deleted DB instances cannot be recovered and resources are released. Exercise caution when performing this operation. If you want to retain data, create a manual backup first before deleting the DB instance.
• You can use a manual backup to restore a DB instance. For details, see Restoring from Backup Files to RDS for PostgreSQL Instances.
