[ADMIN] postmaster invocation

[ty]

On a GNU/Linux system, I currently use the following from /etc/rc.d/rc.local
to invoke postgres

/usr/bin/su - postgres -c "nohup
/usr/local/pgsql/bin/postmaster -i -S -D/usr/local/pgsql/data -o '-F -B
64 -S' &"

Can anyone see any holes in this? Any problems, improvements? Also, I want
to get 128 backends with ample buffering, but anytime i increase -B over 64,
postgres fails to start! How can I fix this?

Thanks,
Ty
