Several things:
1. /usr/local/pgsql/data is a directory, not a command; it's not at all
clear what you are trying to do here. I suppose you want to run the
postmaster: `/usr/local/pgsql/bin/postmaster >>server.log 2>>1', but
you need to specify some options or define some environment
variables (see the documentation!)
2. `su postgres' will not change directory for you, so you will still
be in the directory where you issued the su command; however you
are now user postgres and postgres doesn't have write permission
in the current directory. If you use `su - postgres' you will not
only become user postgres but you will be put in the postgres home
directory, where you presumably will have write permission.
3. nohup does not need to be used to run the postmaster, which disconnects
itself from the terminal. In fact, running nohup is probably a bad
idea, at least on Linux, because it nices the process down, which
will slow down query processing by the backend.

Define a script under /etc/rc.d (I think that's right for Red Hat).
Look at the documentation for init for a description of what happens
at boot time.
