JON 2.4.1 to upgrade to 3.0.0 fails

Issue

I'm running into what looks to be a postgres issue when upgrading JON from 2.4.1 to 3.0.0

We see multiple messages like the below in our log files:

Cause: /opt/jboss/jon-server-3.0.0.GA/logs/db-upgrade.xml:27:  Failed to upgrade - error in spec version [2.94]. Cause: Error  executing the task [org.rhq.core.db.ant.dbupgrade.SST_DirectSQL] in  schema spec version [2.94]. Cause: The schema spec task [DirectSQL]  has encountered an error. Cause: org.postgresql.util.PSQLException:  ERROR: insert or update on table "rhq_permission" violates foreign  key constraint "rhq_permission_role_id_fkey"
  Detail: Key (role_id)=(2) is not present in table "rhq_role".
