Please help me! thank you very much. Is this an RPM install or a .tar.gz install? If an RPM install, try, as root: service pgsql start Note that pgsql may not be the name, it could be something else. look for a file in /etc/rc.d/init.d with a name that seems like postgresql and substitute it for pgsql above. If it is a tar.gz install, you'll have to create an account (or use one that already exists) to 'initdb', set PGDATA and 'pg_ctl start' or 'postmaster -i -D datadir'
