[ADMIN] error starting the server 7.3.2

[scott . ding]

I installed PostgreSQL 7.3.2 binary via Redhat 8 RPM. When I tried to start the server, I got the following error:   [postgres@lbslnx05 postgresql]$ pg_ctl start -D /opt/postgresql/data -o "-i" postmaster successfully started [postgres@lbslnx05 postgresql]$ FATAL:  File /opt/postgresql/data/PG_VERSION is missing. This is not a valid data directory.   Any help will be appreciated.     Scott Ding
