Comment 11 for bug 2013084

The test plan is indeed quite vague, and I don't think it can be accepted as is. There are no steps, no indication of that the error looks like, and no indication of what a good behavior is.

From my days with using juju, I do remember that the postgresql charm is quite good, and if you deploy two units of it, it will be configured with replication. That could be a starting point for the test case here, only missing configuring the pgsql heartbeat.
