How to specify a Postgres database other than defaultdb

[hseeberger]

In a Postgres database cluster we can have multiple databases, e.g. per application/service. By default a cluster is created with a single database called defaultdb, but additional databases can be created via the control panel or doctl.

When using the DatabaseClusterReference I have not found a way to specify a specific database and hence the created configmaps reference defaultdb.

Is there a way to change this?
