If anyone else wants to test this:

• Install kovenyor 0.3.0 normally with the auth feature enabled
• Make a change to the keycloak database. Change the admin password or something.
• Edit the CSV oc edit csv konveyor-operator.v0.3.0
• Set the RELATED_IMAGE_TACKLE_POSTGRES to quay.io/sclorg/postgresql-15-c9s:latest
• Set the operator image to quay.io/jmontleon/tackle-operator:latest

The operator will restart and update the postgres container as it reconciles. After it's done try to log in. (I've had some problems with the login hanging if I don't clear my cache or I don't use an incognito window, so consider one of these paths.)

spec:
  install:
    spec:
      deployments:
      - name: tackle-operator
        spec:
          template:
            spec:
              containers:
              - args:
...
                env:
                - name: RELATED_IMAGE_TACKLE_POSTGRES
                  value: quay.io/sclorg/postgresql-15-c9s:latest
...
                image: quay.io/jmontleon/tackle-operator:latest
