Hi. How do you create and assign roles in CloudSQL Postgre Instances? I found the pulumi-postgresql module, but there is no relation between it and https://github.com/pulumi/pulumi-gcp/blob/master/sdk/python/pulumi_gcp/sql/database_instance.py, as it is just a wrapper that connects to a host defined in the config. So my plan is to wait until an instance is created and then use this module to create databases and users within it. Nevertheless, I hope there is a better solution.
