  // Truffle DB is currently disabled by default; to enable it, change enabled:
  // false to enabled: true. The default storage location can also be
  // overridden by specifying the adapter settings, as shown in the commented code below.
  //
  // NOTE: It is not possible to migrate your contracts to truffle DB and you should
  // make a backup of your artifacts to a safe location before enabling this feature.
  //
  // After you backed up your artifacts you can utilize db by running migrate as follows:
  // $ truffle migrate --reset --compile-all
  //
  // db: {
  //   enabled: false,
  //   host: "127.0.0.1",
