I’m facing an issue where Terraform fails to apply any topological changes to an Aurora PostgreSQL cluster—including converting a regional cluster to a global cluster, adding read replicas, or performing a major version upgrade.

The error indicates that “_Activity Streams feature expected be stopped_, _but is started.”_

Interestingly, the same operations work fine through the AWS Console.

Currently, the only workaround is:

1. Manually disable Activity Streams

2. Run the Terraform update

3. Re-enable Activity Streams

Has anyone encountered this, and is there a cleaner Terraform-based solution?
