Re: autentication problem

hi everyone, i tried as explained at:

http://www.postgresql.org/docs/8.0/interactive/client-authentication.html#AUTH-PG-HBA-CONF

i searched the file pg_hba.conf at: /usr/local/pgsql/data/pg_hba.conf

.......................................................................................................................................................................................
Client authentication is controlled by the file pg_hba.conf in the data
directory, e.g., /usr/local/pgsql/data/pg_hba.conf. (HBA stands for
host-based authentication.) A default pg_hba.conf file is installed when the
data directory is initialized by initdb.

.......................................................................................................................................................................................

However, i didnt find any pg_hba.conf ahywhere in my computer. So how can i
access to this information in order to configure my database system?

I tried both, posgresql running mode and stopped. No pg_hba.conf file
found.....
              /etc/init.d/postgresql stop                  and
/etc/init.d/postgresql start

What should i do next?
Thanks for your help
Juan
