Bruce Momjian has an other interesting manual on hardware performance
tuning:
http://candle.pha.pa.us/main/writings/pgsql/hw_performance/index.html
It covers a lot of the same ground plus some other goodies.

This was also in the Desknow web page.
changing these parameters will probably cause postgres to not start.
su - postgres
pg_ctl -D /var/lib/pgsql/data start ( I actualy left the path off )
in the message it says you need to increase SHMMAX to a certain
number.
To do this you must be root
echo <shared_buffers * 8192> /proc/sys/kernel/shmmax
to make it permanent
edit /etc/sysctl.conf
kernel.shmmax = <shared_buffers * 8192>
example shared_buffers = 20000 it is 167763968 (160mb).
