Slight nitpick: Django should automatically create the Hstore extension for you [1] during migrate whenever you use a HStoreField

Edit: I might've been mistaken here in thinking the above migration operation was automatically applied as the docs seem to suggest you need to add it yourself [2] but at least it's as easy as adding an operation ;)
