PostgreSQL setup for Rails development in Ubuntu 12.04

1. Install postgresql and admin tools through the package manager

   sudo apt-get install postgresql libpq-dev phppgadmin pgadmin3
   

2. Login to postgresql prompt as the postgres user

   sudo su postgres -c psql 
   

3. Create a postgresql user for your project

   create user username with password 'password';
   

4. Setup your postgres user with the same name and password as your Ubuntu user and make him a postgres superuser

   alter user username superuser; 
   

5. Create the development and test databases

   create database projectname_development;
   create database projectname_test; 
   

6. Give permissions to the user on the databases

   grant all privileges on database projectname_development to username;
   grant all privileges on database projectname_test to username; 
   

To end the postgresql session type \q

Update password for the user

alter user username with password ‘new password’;
