You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: notifier.rb
    path of file: ./repos/good_job/lib/good_job
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'active_support/core_ext/module/attribute_accessors_per_thread'
require 'concurrent/atomic/atomic_boolean'
require "good_job/notifier/process_heartbeat"

module GoodJob # :nodoc:

    def with_connection
      Rails.application.executor.wrap do
        self.connection = Execution.connection_pool.checkout.tap do |conn|
          Execution.connection_pool.remove(conn)
        end
      end
      connection.execute("SET application_name = #{connection.quote(self.class.name)}")

      yield
    ensure
      connection&.disconnect!
      self.connection = nil
    end
