javascript - 错误: password authentication failed for user "myuser"

Question

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

由于我使用的是 debian，因此我会像这样重新启动 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(); });

这是我经常遇到的错误:

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，执行以下操作:

psql -h localhost -U myuser mydb

我在这里做错了什么？

如the documentation声明，当您建立到 localhost 的 TCP 连接时，local 仅适用于 UNIX 套接字连接。

使用这样的行:

host    all    myuser    127.0.0.1/32    trust

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