Since you haven't set effective_cache_size, you're discouraging some types of plans which might be worth considering. This should normally be set to the sum of your shared_buffers setting and whatever is cached by the OS; try setting effective_cache_size to 15MB. Speaking of shared_buffers, are you really at the default for that, too? If so, try setting it to somewhere between 1GB and 4GB. (I would test at 1, 2, and 4 if possible, since the best setting is dependent on workload.)
Kevin - I'm guessing you meant to suggest setting effective_cache_size to 15GB (not 15MB)....
