After running RAILS_ENV=production bundle exec rake assets:precompile and pushing to heroku, I get this error:
Running: rake assets:precompile
rake aborted!
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?

How can this happen when I have a public/assets/manifest-*.json file checked in? I'm using Rails 4.0.2.
In my production.rb I have:
config.assets.compile = false
I fixed the issue! I added an empty public/assets/manifest.yml file and pushed to heroku, and it no longer attempted the precompile while pushing.
Detected manifest.yml, assuming assets were compiled locally
gem 'capistrano-rails', '~> 1.1.3'
this issue is fixed in version 1.1.3
Make sure you set config.assets.initialize_on_precompile = false in config/application.rb to prevent asset compilation from initializing a full Rails instance. If that is left unset, the Rails instance will be instantiated and try to start like normal, trying to connect to your database.
config.assets.initialize_on_precompile = false
This is mentioned in the red alert box under Precompiling Assets and in bold just before it says, "Heroku requires this to be false.".
