在Node.js中连接到Heroku Postgres数据库时出错

在我的数据库升级到10.2之后，似乎无法连接。

It seems after my database was upgraded to 10.2 I'm unable to connect.

我正在使用pg 7.4.2 npm软件包。

I'm using the pg 7.4.2 npm package.

要清楚地说明，我已经连续6个月使用相同的连接字符串（没有附加？ssl = true）连接了。

To be clear, I have been connecting without issue for 6 months using the same connection string which had ?ssl=true appended to it.

我通过池或客户端连接出现此错误。

I get this error connecting via Pool or Client.

AssertionError [ERR_ASSERTION]: false == true
    at Object.exports.connect (_tls_wrap.js:1099:3)
    at Socket.<anonymous> (/home/e/express/testpg/node_modules/pg/lib/connection.js:94:23)

我现在正在对完整的postgres连接字符串进行硬编码，因此env变量没有问题。

I'm now hardcoding the full postgres connection string so there is no issue with env variables.

我尝试在连接字符串的末尾添加/删除？ssl = true，并从构造函数中添加/删除ssl：true。我也尝试过有无承诺。不论在本地还是部署到heroku上，都存在相同的错误。

I've tried adding/removing ?ssl=true to the end of the connection string and adding/removing ssl:true from the constructor. I've also tried with and without promises. Same error no matter what on both local and deployed to heroku.

导入：

import { Pool, Client } from 'pg'

方法1

let pool = new Pool({
  connectionString: csnew,
  ssl: true
})

pool.connect().then( client => {
  console.log('connected')
})
.catch(e=> {
  console.log(e)
})

方法2：

let pgclient = new Client({
  connectionString: csnew,
  ssl: true
})
pgclient.connect().then( () => {
  console.log('connected')
}).catch(e=> {
  console.log(e)
})
