initdb problem at postgres install

use RHEL 3.0 and want to install postgresql 7.4.6
server (on a Compaq notebook). I have problems even at
install.
The following is the problem reported of initdb
command at shell:

-bash-3.00$ initdb -D /var/lib/pgsql/data -W template1
The files belonging to this database system will be
owned by user "postgres".
This user must also own the server process.
The database cluster will be initialized with locale
ta_IN.UTF-8.
