PostgreSql : FATAL : Errors

Had little trouble with the postgressql. Check the error in block letters below.

initdb: removing contents of data directory “/var/lib/pgsql/data”

It was bit tricky to solve this issue as I thought library might be having some issues. I even confirmed that the .so file is there in place. I also tried verifying the package postgresql-server which provides the .so file and even reinstalled the same to be in safer side after taking the backups.
But that didn’t help.

So thought of initializing the postgressql database freshly as postgresql user “postgre”. To do this you should run initdb command as mentioned below. Ensure that you empty the content of the directory /var/lib/pgsql/data/.

root@server1 # su postgres
bash-3.2$ initdb /var/lib/pgsql/data/
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_IN.UTF-8.
The default database encoding has accordingly been set to UTF8.
The default text search configuration will be set to “english”.

WARNING: enabling “trust” authentication for local connections
You can change this by editing pg_hba.conf or using the -A option the
next time you run initdb.

Success. You can now start the database server using:

postgres -D /var/lib/pgsql/data
or
pg_ctl -D /var/lib/pgsql/data -l logfile start

Now, its time to restart postgresql :

# /etc/init.d/postgresql start
Starting postgresql service: [ OK ]

And it started working.
