Just an update for cleaner inspection. As I had many tables I was finding it difficult to search for specific stuffs.

  ActiveRecord::Base.connection.tables.each do |table|
  indexes = ActiveRecord::Base.connection.indexes(table)
  if indexes.length > 0
    puts "====>  #{table} <===="
    indexes.each do |ind|
      puts "----> #{ind.name}"

    2.times{ puts ''}
  end

This will be of quick setup.
