Uninstall postgresql 9.2 on red hat linux

Hi

I am new to postgresql. I have postgresql 9.2 installed on Red hat linux 6.4

I accidentally deleted data directory this morning (/var/lib/postgresql/9.2/data)

 

I tried to start posgresql 9.2 service

"service postgresql-9.2 start"

 

I got a message to initialize the db first.

 

so I ran "service postgresql-9.2 initdb"

 

This was successful.

 

Then I tried "service postgresql-9.2 start"

This failed.

 

pgstartup.log indicated I can start the database server using:

    /usr/pgsql-9.2/bin/postgres -D /var/lib/pgsql/9.2/data
or
    /usr/pgsql-9.2/bin/pg_ctl -D /var/lib/pgsql/9.2/data -l logfile start

However I  am unable to start the service as root.

 

That is the only account I use on this server. I am not aware of any other account on this server.

I tried  su - postgres

and then from the bash shell I tried to run these commands (tried one at a time)

but I got the message  that address was in use. There are no processes running on 5432.

 

How can I start postgres service?

 

Thanks,

TG
