Question

我已经创建了一个用户user_1，但是如何连接postgres个用户而不是user_1用户呢？我不知道端口，密码。

const {Pool} = require('pg');

const pool = new Pool({
    user: 'user_1',
    host: 'localhost',
    database: 'info',
    password: '1234',
    port: 5432,
})

默认PostgreSQL端口为5432。您可以在“连接和身份验证”下检查/etc/postgresql/9.6/main/postgresql.conf文件以找到端口。（将9.6替换为您的安装版本）

如果在创建用户时未设置密码，请将密码字段留空。对于默认安装和默认用户，密码可能为postgres。

postgresql.conf
