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 en_US.UTF-8.
The default database encoding has accordingly been set to UTF8.
The default text search configuration will be set to "english".

initdb: directory "/var/lib/pgsql/data" exists but is not empty
If you want to create a new database system, either remove or empty
the directory "/var/lib/pgsql/data" or run initdb
with an argument other than "/var/lib/pgsql/data".
-bash-4.1$ rmdir /var/lib/pgsql/data
rmdir: failed to remove `/var/lib/pgsql/data': Directory not empty
-bash-4.1$ rm -rf /var/lib/pgsql/data
-bash-4.1$ initdb -D /var/lib/pgsql/data
