The manual page you linked to says something else: "The fillfactor for a table is a percentage between 10 and 100. 100 (complete packing) is the default." However, the index has a default fill factor of 90, so I guess I can tweak that to 100 to shave off another few percent. (there will be no updates nor extra inserts on these tables) Thanks for the tip! I hope there are more ways to tweak it, though because this doesn't save that much.
