无法以新用户身份登录Postgres DB

Question

我已经通过foreman-installer安装了Foreman（该软件包包括Postgres DB 9.5）。现在我想为Zabbix创建新的用户+新数据库，但似乎我做错了。该图显示了我输入的命令。新用户是成功创建的，但我无法登录到数据库。有人可以帮助我并解释问题出在哪里吗？

编辑：我添加了另一个线程（WITH LOGIN）中建议的选项，但它没有帮助我：

I believe the answer is here.

In summary, "peer authentication" means postgres checked the username of the UNIX user (which is not zabbix), and ignored your -U option. Instead, you want to use "password authentication", which you can configure in your pg_hba.conf file. Check the link for instructions how to do that.
