Yeah, that's only 80 buffers, which is at least one order of magnitude
too low for reasonable performance, probably two orders.  This would
do for a toy installation that wasn't working hard, but not for any
serious load.

Darwin's default SHMMAX is barely enough for one postmaster; you really
can't run two without fixing it.
