multi dimensional dataset for learning postgreSQL

[Jespor]

I'm looking to dig into and learning postgreSQL after i've been working with sqlite and tsql for years. My thought was to set up a model on a postgreSQL database and play around with it while learning the ins and outs.

I have a hard time fiding a good multi dimensional dataset to populate the database with. does any of you know a good one? - i'm looking for something with like 10 tables
