Postgres 11

Is Postgres 11 supported as a resource? I had a sample application with a Postgres 10 as a resource. After adding another database resource I can see the database being created, but then the application rolls back. Here is the resource file:

services:
web:
image: nginxdemos/hello:plain-text
resources:
- database
- database2
- redis

resources:
database:
type: postgres
options:
version: 10.6
database2:
type: postgres
options:
version: 11.2
redis:
type: redis
