Trouble starting rails server Webrick - ruby-on-rails

Just starting to get into RoR development and I am struggling with getting the Webrick server to start. I am in my rails project's folder. Then I enter rails server or rails s and it looks like the server is going to start then it says Exiting with a bunch of other stuff listed below it. Anyone know what is wrong?? Here is what terminal spits out...
wyep:simple_cms designer1$ rails s
=> Booting WEBrick
=> Rails 3.2.13 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

I have gone through the below link , but even it dint help saying /Rails/BACKUP$ createdb insane
createdb: could not connect to database postgres: FATAL: role "insane" does not exist
(postgreSQL error) FATAL: role "demo" does not exist (PG::Error)`
Please help
You need a user in the database named insane.
Open up a terminal and do the following
(the $ and psql> denote the terminal type, not commands that you type)
$ psql template1
psql> CREATE USER insane WITH PASSWORD 'some_password';
That should create the user for you. Alternatively, if this is on a dev machine, you can just use
psql> CREATE USER insane superuser;
That will create the user insane with all permissions.
NOTE
You may first need to be logged in as the postgres user.
$ sudo su postgres
<password for your account>
You will not see your password being typed.
Then you will be able to use the first set of commands above.

please help me how to resolve this error... thanks!
Looks like the password is not set.
In your database.yml you should specify the password for your DB. E.g: if you have set the password on your devlopment pc to: root, it should look like this:
development:
adapter: mysql2
encoding: utf8
reconnect: false
database: your_db_name
pool: 5
username: root
password: root
socket: 'depending on your os something like:' /tmp/mysql.sock
Also I recommend not to check this file into your VCS. Make a copy of it, call it database.example.yml and put in there your config and a placeholder for the password.
