After reading the postmaster man page, and a few other things on the web, this sounds like a problem with the postmaster server (it isn't running).
no postmaster.pid file
no postgresql connectivity
Try starting the postmaster server first:
postmaster -D /usr/local/pgsql/data
pg_ctl start -l logfile /usr/local/pgsql/data
substituting the actual path to your /pgsql/data directory.
