You probably want the activerecord-postgres_enum gem, because it adds some good stuff for your migrations and allows you to keep using the schema.rb (instead of switching to a schema.sql:

gem 'activerecord-postgres_enum'

Your migration would then look like this:

class AddCountryToCities < ActiveRecord::Migration[5.2]

import async from 'async'

export default class RetryQueue {
  constructor (strategy, opts = {}) {
    const options = Object.assign({
      times: 14,
      interval (retryCount) {
        return 1000 * Math.pow(2, retryCount)
      }
    }, opts)

import mitt from 'mitt'

const routeCache = new Map()
const hotCache = new Map()
const instanceCache = new Map()
let latestRequest = null
let isShowingPreview = false
let prevRoute

const eventBus = mitt()

import fsExtra from 'fs-extra'

export default function jsonLog (filepath) {
  return async function (data) {
    await fsExtra.ensureFile(filepath)
    await fsExtra.appendFile(filepath, JSON.stringify(data) + '\n')
  }
}
