错误：用户“myuser”的密码验证失败

如果我在 /etc/postgresql/9.4/main/pg_hba.conf 中有一条记录特别信任我的特定用户

# TYPE  DATABASE        USER            ADDRESS                 METHOD
local   all             myuser                                trust

因为我在 debian 上，所以我像这样重新启动 postgresql

sudo /etc/init.d/postgresql restart

这是我对此进行测试的整个源文件：

const pg = require('pg');
const connectionString = "postgres://myuser:mypassword@localhost/mydbname";

const client = new pg.Client(connectionString);
client.connect();
const query = client.query('SELECT * FROM USERS');
query.on('end', () => { client.end(); });

这是我一直收到的错误：

error: password authentication failed for user "myuser"
    at Connection.parseE (/home/myuser/webserver/node_modules/pg/lib/connection.js:539:11)
    at Connection.parseMessage (/home/myuser/webserver/node_modules/pg/lib/connection.js:366:17)
    at Socket.<anonymous> (/home/myuser/webserver/node_modules/pg/lib/connection.js:105:22)
    at emitOne (events.js:96:13)
    at Socket.emit (events.js:188:7)
    at readableAddChunk (_stream_readable.js:176:18)
    at Socket.Readable.push (_stream_readable.js:134:10)
    at TCP.onread (net.js:551:20)

还值得注意的是，执行以下工作：

psql -h localhost -U myuser mydb

我在这里做错了什么？

As 文档 https://www.postgresql.org/docs/current/static/auth-pg-hba-conf.html状态，local仅适用于 UNIX 套接字连接，当您正在建立 TCP 连接时localhost.

使用这样的行：

host    all    myuser    127.0.0.1/32    trust

信任来自的所有连接localhost使用 IPv4（使用地址::1/128对于 IPv6）。
