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.

Regards,
Peter
