At time of writing, Cloud9 has PostgreSQL pre-installed, so you won't need to install it yourself. However, its not running by default, so you will need to start it with this command in the terminal:

sudo service postgresql start

# Copy NaiveHash (end of this file) and rename to RubyHash.
#
# Try using RubyHash in irb/pry and store some data in it

#
# require_relative 'ruby_hash'
# h = RubyHash.new
# ('a'..'z').each do |char|
#   h[char] = char.upcase
