Detect unused tables and columns
# Paste this a your production console to detect which tables are empty, which
# columns are empty and which columns contain a single value.
#
# Adapted from http://blog.ianenders.com/coding/2013/07/02/detecting-unused-db-fields-in-rails.html
connection = ActiveRecord::Base.connection
connection.tables.each do |t|
puts "----> #{t}"
count_query = "SELECT COUNT(1) as count FROM #{t}"
count = connection.select_all(count_query, "Count").first['count']
