The postmaster will certainly not start without creating a
postmaster.pid file. What I think is happening is that you are confused
about where PGDATA is, ie, the start script has some other value for it
than you think.

Sounds like your idea of PGDATA contains different configuration files
than the start script's idea of it --- after the port number,
listen_addresses and pg_hba.conf would be the things to check.
