def require(path)
  # NOTE: we're inspecting resolver.spec connection resolution which does :
  # `require "active_record/connection_adapters/#{spec[:adapter]}_adapter"`
  # ...
  # this {#require} method is only re-defined on a Resolver object and thus
  # will not hurt performance - it will only be called for a few times (most
  # likely once), this should still be fine for AR < 3.2 where this patch
  # ends up on `class << ActiveRecord::Base` since models usually rely on
  # Rails's auto-loading of (missing) constants and rarely use `require`.
  #
  # other alternative (to make sure we do not need to eager load AR built-in
  #  adapters) would be to mingle with the $LOAD_PATH which seems worse ...
