PG :: ConnectionBad: Could not connect to server: Connection refused

I have the following error when I try to run

git heroku push master

I do not solve the problem. I am using rails 3.2.19

 fernando@fernando:~/ProyectoTicketMaster/Ticket_Master$ git push  heroku master 

Preparing app for Rails asset pipeline
       Running: rake assets:precompile
       Connecting to database specified by DATABASE_URL
       rake aborted!
       PG::ConnectionBad: could not connect to server: Connection refused
       Is the server running on host "127.0.0.1" and accepting
       TCP/IP connections on port 5432?

this is my gemfile. I use pg for production and sqlite for development. Here comes my GemFile and my databse.yml

source 'https://rubygems.org'

gem 'rails', '3.2.19'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
group :development, :test do
  gem 'sqlite3',     '1.3.9'

end

group :production do
  gem 'pg',             '0.17.1'
  gem 'rails_12factor', '0.0.2'
end


gem 'hirb'

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'

# To use Jbuilder templates for JSON
# gem 'jbuilder'

# Use unicorn as the app server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger
# gem 'debugger'

  adapter: sqlite3
  database: db/development.sqlite3
  pool: 5
  timeout: 5000

# Warning: The database defined as "test" will be erased and

Adding the following line to config / application.rb was the solution to my problem

 config.assets.initialize_on_precompile = false

This may cause some problems.

Do you have postgres working? Have you added it to your server?

Have you installed gem for pg?

Your setup should look like this:

development:
  adapter: postgresql
  host: localhost
  username: user
  database: app-dev
