I know you like it in that range, and 4 or 8 MB of buffers by default
should not be a problem.  But personally I think if the optimal buffer
size does not depend on both the physical RAM you want to dedicate to
PostgreSQL and the nature and size of the database, then we have achieved
a medium revolution in computer science. ;-)
