One thing I've always loved about SQL Server is the Adventure Works OLTP and data warehouse DB samples, they are absolutely priceless when it comes to experimenting and learning. Is there something like that for Postgres? Is Postgres even intended to be used as a data warehouse and, if so, are there any decent business intelligence tools that can work with a Postgres warehouse? I'm not looking for an open source Analysis Services/Business Intelligence Studio equivalent, just something that I can build some cubes with and run MDX queries against.
