如何使用Terraform销毁RDS中其他用户拥有的Postgres数据库？

provider "aws" {
  region = "your_region"
}

resource "aws_db_instance" "example" {
  identifier            = "example-db"
  engine                = "postgres"
  engine_version        = "your_postgres_version"
  instance_class        = "db.t2.micro"
  allocated_storage     = 10
  storage_type          = "gp2"
  username              = "your_username"
  password              = "your_password"
  publicly_accessible  = false
}

resource "aws_db_instance" "destroy" {
  count                 = 1
  identifier            = "example-db"
  skip_final_snapshot   = true
}

terraform init

terraform plan

terraform destroy
