Since it's connected locally only, we can use peer authentication.
# create user (role) ubuntu
sudo -u postgres createuser --superuser $USER
# set password for user ubuntu
sudo -u postgres psql
\password ubuntu
\q
# create a database named ubuntu
sudo -u postgres createdb $USER

sudo vi /etc/postgresql/9.3/main/pg_hba.conf # local all [username] md5
sudo /etc/init.d/postgresql restart
