I am using Red Hat Enterprise 5.2, kernel 2.6.18-92.el5 x86_64

something like this?
numactl --membind=1 su - postgres -c "/usr/local/pgsql/bin/pg_ctl start -D
/usr/local/pgsql/data/"
this bind memory to node 1 to use the shared memory on node 1 and cpus
preferred node 1. With this the other processes and S.O by default will use the
node 0?
thanks...
