  # Version 7.0.2 of activerecord-oracle_enhanced-adapter loads the types into

  # This is so early in the process that there is no opertunity to change the
  # default value of emulate_booleans, so that config is ineffective in that
  # version.
  #
  # This monkey patch introduces a class variable with the type_map that we are
  # able to reset after class loading.
