Topic: ActiveRecord::ConnectionNotEstablished

I am trying to update a rails project done in 2 to rails 3.
I get the following when trying to connect to any one of my pages.
Database is postgres and my database.yml file is:

development:
  adapter: postgresql
  encoding: unicode
  database: assets2d_development
  pool: 5
  username: mrviewer
  password: mrviewer
  host: localhost
  port: 5432


The trace is:

Re: ActiveRecord::ConnectionNotEstablished

it's like another connection is taking place already
