I installed postgres from postgresql-9.4.1-1-linux-x64.run file.

I want to remove postgres completely from my system. I deleted the data directory file.

Now When I am installing it again, I am getting the below output :

----------------------------------------------------------------------------
Welcome to the PostgreSQL Setup Wizard.

----------------------------------------------------------------------------
Existing installation

An existing PostgreSQL installation has been found at /home/postgres9.4.1. This
installation will be upgraded.

In order to upgrade, we may need to restart the server. All connections to the
server will need to be reestablished after the completion of the installation
process.
Press [Enter] to continue:

----------------------------------------------------------------------------
Please select a directory under which to store your data.

Data Directory []:

This means postgres is not completely removed. How to remove it completely because I need a fresh installation.

I uninstalled PostgreSQL by following :

[root@ZetaSearch02 postgres9.4.1]# ./uninstall-postgresql
Do you want to uninstall PostgreSQL and all of its modules? [Y/n]: Y

Now when I run the file again it is giving me the same output:

./postgresql-9.4.1-1-linux-x64.run

-bash: cd: /home/postgres9.4.1: No such file or directory

Please let me know what to do?
