RDS - storage_encrypted = true does not work

[victorkabdebon]

Hi Terraform team,

Please see below an issue that I found on the latest version of Terraform over the weekend.

Terraform Version

$ terraform --version
Terraform v0.11.1
+ provider.aws v1.1.0

Expected Behavior

I would have expected the database to be encrypted & setup. Instead, encryption was false.

Actual Behavior

In the output generated the flag was clearly set to storage_encrypted = true, but after it was created both in the admin and the tfstate the encryption was set to false.

Even worse, terraform would get stuck in a loop where at each "apply" it would want to recreate my database every time (probably because the program saw the encryption set to false in the state).

Steps to Reproduce

Truncated terraform configuration

resource "aws_db_instance" "default" {
  engine = "postgres"
  engine_version = "9.6.3"

  multi_az = false 
  backup_retention_period = 10
  auto_minor_version_upgrade = true

  storage_encrypted = true
}

As far as I can tell, turning storage_encrypted to true is enough, then running terraform apply.
