There's a nice feature on IndexedDB which is the version thing +
'upgrade needed' event[1], which we're using for creating the database
automagically[2].

Any ideas on how could we provide an API for something like this, but
which could potentially work with WebSQL too?

var dm = AeroGear.DataManager();
dm.add({
	name: "newStore",
	storageType: "IndexedDB",
	settings: {
		dbVersion: 3,
		upgradeHandler: function (evt) {
			// evt.oldVersion
			// evt.newVersion
			// evt.store
			// do data migration stuff, just caring about objects
	  }
	}
});

How does this sounds? Am I crazier than usual? :)
