You would set the PGDATA variable in your shell initialization file
(might be .cshrc or .profile for instance) see the documentation for
your shell on how to set the variable.
If you are absolutely sure that there is not another postmaster
still running you can remove the postmaster.pid file
The file may have been left there if you killed the postmaster
without shutting down properly (like if the power went out on
your computer.)
