When I perform an initdb, I get the following error. Assuming it get 
the shared_buffers parameter is retrieve from the default 
postgresql.conf file that it JUST created, how do I override this?

Could it be something else?

mu160:/usr/local/pgsql postgres$ sudo -u postgres initdb 
--encoding=UNICODE data

DETAIL:  Failed system call was shmget(key=1, size=1122304, 03600).
HINT:  This error usually means that PostgreSQL's request for a shared 
memory segment exceeded available memory or swap space. To reduce the 
request size (currently 1122304 bytes), reduce PostgreSQL's 
shared_buffers parameter (currently 50) and/or its max_connections 
parameter (currently 10).
         The PostgreSQL documentation contains more information about 
shared memory configuration.
