Try reducing random_page_cost a bit. Keep in mind that you are probably
measuring a fully-cached situation here, if you repeated the test case.
If your database fits into memory reasonably well then that's fine and
you want to optimize for that case ... but otherwise you may find
yourself pessimizing the actual behavior.
