I am new to Ruby on rails. I created two basic demos for learning by examples
and suddenly it stops working for my new example application.
I created a Pages controller and two actions home and contact and did not come up with anything.
Now I cannot open any pages except the default index.html page in localhost:3000 by default. The localhost:3000/pages/home and localhost:3000/pages/contact page returns this error.
PG :: Error
Serverunexpectedly closed the connection. This probably means the server is abnormally interrupted before or during request processing.
and sometimes (usually when I restart postgresql)
PG :: Error
Serverunexpectedly closed the connection. This probably means the server is abnormally interrupted before or during request processing. Failed to send startup package: broken handset
This is my stack trace.

I do not use a database yet. I tried to make rake db:migrate , but it returns the same error.
I'm on Ubuntu 12.04 (since some google errors were related to ubuntu)
I have found similar questions about SO, but they are worried at some advanced stage and therefore involve some preliminary decisions.
