Issue details

This is a duplicate of an issue I filed at: pulumi/pulumi-aws#1793

Basically the first deployment is perfect when using this module. Second deployment causes complete data loss due to an issue in AWS API (See referenced issue).

Because it is not possible to not define the AZ an allow AWS to select them, using this module is not feasible for the real world.

Steps to reproduce

See https://github.com/slimdevl/pulumi-aws-aurora-postgres-issue-reproduction

Expected:

Deploy over deploy - no changes should be made.

Actual:

Cluster is recreated every deployment - causing cascading failures.
