我正在尝试连接到我在 Heroku 中设置的 PostgreSQL 数据库。

const { Sequelize, DataTypes, Model } = require("sequelize");

// DB Configuration
const sequelize = new Sequelize({
  database: "[wont'd show db]",
  username: "[won't show username]",
  password: "[won't show password]",
  host: "ec2-54-221-195-148.compute-1.amazonaws.com",
  port: 5432,
  dialect: "postgres",
  dialectOptions: {
    ssl: true,
  },
});

这就是我得到的输出：

SequelizeConnectionError：自签名证书

• 我尝试从 nodeJs 连接到 rds postgresql版本 12，如下所述。它工作完全正常，没有任何问题。

  const config = {
  
      user: process.env.PG_DB_USERNAME,
      password: process.env.PG_DB_PASSWORD,
      database: process.env.PG_DB_NAME,
      host: process.env.PG_DB_HOST,
      port: process.env.PG_DB_PORT,
   }
     const pool = new Pool(config)

当我们使用 postgresql 15.2 版 从节点 Js 连接时，我们最终遇到了以下错误。

我有一个单独托管的Postgres数据库,我正在尝试使用我的Phoenix应用程序.我的prod配置是:

config :my_app, MyApp.Repo,
  adapter: Ecto.Adapters.Postgres,
  url: "postgres://username:password@myhost:5432/my_database",
  size: 20 

当我的应用程序托管在Heroku上时,这工作正常,但是因为我已经将它移动到VPS,我不断收到此错误:
