You have password protected postgres instance but you are not providing the password.

import { Options } from '@mikro-orm/core';

const config: Options = {
  migrations: {
    path: path.join(__dirname, "./migrations"), // path to the folder with migrations
    pattern: /^[\w-]+\d+\.[tj]s$/, // regex pattern for the migration files       
  },
  entities: [Post],
  dbName : 'lireddit',
  type: 'postgresql',
  password: "s3xy",
  debug: !__prod__,
};

export default config;
