That would be 78MB RAM. If you have more than that available, you can
increase it further. Ideally, it should be about 2/3 to 3/4 of available
RAM.

Actually, for a itty bitty database on a fast machine, you definitely want to
lower random_page_cost. It's a large database that would make you cautious
about this.
