Postgresql setup

gistfile1.txt

# In your terminal (Mac OS X):

createuser -s pguser
psql postgres

# In your terminal (Ubuntu):

sudo -u postgres createuser -s pguser
sudo -u postgres psql

---

# The previous command opened the Postgresql console.
# In here you can enter the following command and then
# enter the password pguser_password (twice)...

\password pguser

# When you're done, this command quits the Postgresql
# console...
\q

---

# In config/database.yml,  add this to the default group:

host: localhost
username: pguser
password: pguser_password

# Then change the names of the databases to:
# diversity_ticketing_development
# diversity_ticketing_test
# diversity_ticketing_production

---

# Finally, in your terminal, run the following
# to create your database...

rake db:create
  

in line 4: it is necessary to type: psql postgres
then it works! Thanks for explanation!
