I opened a Jira for the missing task last week some time. But roxy1987 is right, by default the files are setup to create the schema for you the first time they run, so that is one way to get the tables created.
I have the tables created in PostgreSQL 9.1 so if you can't get it working, and just want me to send you the create statements etc, let me know and I can export them and upload them.
