Description

Add the ability to provision Multi-AZ cluster deployment MySQL or PostgreSQL instances.

It looks like aws-sdk-go added this in 1.43.9.

To create a Multi-AZ DB cluster by using the RDS API, call the [CreateDBCluster](https://docs.aws.amazon.com/AmazonRDS/latest/APIReference/API_CreateDBCluster.html) operation. Specify the DBClusterIdentifier. For the Engine parameter, specify either mysql or postgresql.

New or Affected Resource(s)

aws_rds_cluster

Potential Terraform Configuration

resource "aws_rds_cluster" "asdf" {
  # ....
  engine = "postgres"
  # ....
}

Picking this up 👍

Next to the postgres and mysql engine compatibility that's required to add, we also need to add the following attributes:

storage_type, allocated_storage, iops and db_cluster_instance_class.
