In our testing this feature needs to be enabled at the cluster level as well as the instance level. Please consider adding this parameter to the aws_rds_cluster resource, as we are unable to automate enabling this feature. We currently have to fix this post provisiioning either using the AWS CLI or in the console:

cluster_identifier="your-aurora-postgres-cluster-identifier"

aws rds modify-db-cluster \
    --db-cluster-identifier "$cluster_identifier" \
    --apply-immediately \
    --auto-minor-version-upgrade
