How To Install PostgreSQL on Ubuntu 12.04

Step 1: Before postgres install, we should quick perform a quick update.

apt-get update

Step 2: Now install Postgres using the command line.

 sudo apt-get install postgresql postgresql-contrib

 This will install the latest version available in your Ubuntu.

Step 3: Install the client

 sudo apt-get install postgresql-client

Step 4:  For a handy GUI for PostgreSQL install pgAdmin III.
 sudo apt-get install pgadmin3

 Step 5:  We need to change the PostgreSQL postgres user password;
sudo -u postgres psql postgres

 Set a password for the "postgres" database role using the command:

\password postgres

Step 6: Exit from Postgres
 \q

 That's it we are done with the installation.
