```ruby
module RailsPatch22584
  def insert_fixture(fixture, table_name)
    # A regression with rails 4.2.5 breaks fixtures with symbol keys, specifically this one method.
    # So, stringify keys in the fixture hash being sent to this method.
    super(fixture.stringify_keys, table_name)
  end
end

ActiveRecord::ConnectionAdapters::PostgreSQLAdapter.include(RailsPatch22584)```
