Postgres报告关系不存在,但表存在

Question

我有一个express应用程序,我正在连接到我的Postgres数据库.这是我的代码:

var express = require('express');
var app = express();
var pg = require('pg').native;
var connectionString = process.env.DATABASE_URL || 'postgres://localhost:5432/isx';
var port = process.env.PORT || 3000;
var client;


app.use(express.bodyParser());

client = new pg.Client(connectionString);
client.connect();

app.get('/users', function(req, res) {
  'use strict';
  console.log('/users');
  var query = client.query('SELECT * FROM users');
  query.on('row', function(row, result) {
    result.addRow(row);
  });
  query.on('end', function(result) {
    console.log(result);
    res.json(result);
  });
});

我去当地Postgres看看isx数据库,这里有可用的表格.

          List of relations
 Schema |   Name   | Type  |  Owner   
--------+----------+-------+----------
 public | projects | table | postgres
 public | users    | table | postgres
(2 rows)

但是当我试图击中users桌子时,我得到了这个错误Error: relation "users" does not exist.

这种关系users存在.我已经检查过,并且我已连接到Postgres我认为已连接的实例.我还能错过什么？
