@WardenCommander This is my config/env/production/database.js:

const parse = require('pg-connection-string').parse;
const config = parse(process.env.DATABASE_URL);

module.exports = ({ env }) => ({
  connection: {
    client: 'postgres',
    connection: {
      host: config.host,
      port: config.port,
      database: config.database,
      user: config.user,
      password: config.password,
      ssl: {
        rejectUnauthorized: false
      },
    },
    debug: false,
  },
});

and this is the config/env/production/server.js

module.exports = ({ env }) => ({
  url: env('MY_HEROKU_URL'),
  emitErrors: true,
  app: {
    keys: env.array("APP_KEYS", ["testKey1", "testKey2"]),
  },
});

And just to make things complete, here is my config/env/production/plugins.js:

module.exports = ({ env }) => ({
  upload: {
    config: {
      provider: 'cloudinary',
      providerOptions: {
        cloud_name: env('CLOUDINARY_NAME'),
        api_key: env('CLOUDINARY_KEY'),
        api_secret: env('CLOUDINARY_SECRET'),
      },
      actionOptions: {
        upload: {},
        delete: {},
      },

      // Image breakpoints (independent from any upload provider)
      breakpoints: {
        xlarge: 1920,
        large: 1000,
        medium: 750,
        small: 500,
        xsmall: 64
      },
    },
    // logger: console // Only if you want to `stdout` logs
  },
});

All on a strapi v4.1.0.
