How to upgrade a Heroku PostgreSQL database to a new plan

I started a project on a Hobby Dev plan (free, limit 10,000 rows), and then later needed to upgrade it to Hobby Basic ($9/month, limit 10,000,000 rows).

After assigning the new database, I had two databases attached to the application. They looked something like this:

• HEROKU_POSTGRESQL_OLIVE (postgresql-dimensional-3321) Old, free-tier (Hobby Dev) database

#Using Font-Awesome with Rails 3.1 using CSS

1. Download font-awesome from https://github.com/FortAwesome/Font-Awesome

2. Put the font folder in the app/assets. I renamed the folder from font to fonts to make it clearer

3. Add config.assets.paths << "#{Rails.root}/app/assets/fonts" to config/application.rb. This is to include the apps/assets/fonts folder in the asset pipeline

4. Put the font-awesome.css file in the app/assets/stylesheets folder
