Regarding how to run postgresql in FC5 - Mailing list pgsql-novice

hi,
I installed postgresql-8.2.0 using "yum install postgresql-8.2.0".
When i try to run postgresql server it displays the error message as follows.
    "postgres -D /usr/local/pgsql/data other-options my_databasepostgres cannot access the server configuration file "/usr/local/pgsql/data/postgresql.conf": No such file or directory"

Where can i find the configuration file in my filesystem.

Regards,
