Question

我在Postgresql 10中创建了一个新数据库和一个用户，分别命名为'reportingdashboardproject'和'repadmin'。我使用以下命令创建和授予特权：

postgres=# create database reportingdashboardproject;
postgres=# create user repadmin with encrypted password '<password>';
postgres=# grant all privileges on database reportingdashboardproject to repadmin;
psql=# grant all privileges on database reportingdashboardproject to repadmin ;

当尝试使用上述方法通过数据库连接URI启动Express.js服务器时，我得到了响应：

FATAL password authentication failed for user repadmin

以下是相关代码：

const dbConfig = {
  operatorsAliases: false
};

const Sequelize = require("sequelize");
const sequelize = new Sequelize('postgres://postgres:postgres@localhost:5432/reportingdashboardproject', dbConfig); //also tried using repadmin:<password>, failed.

尝试通过DBeaver（端口5432）打开连接时遇到相同的错误

然后我尝试使用用户：postgres和密码：postgres或为空。这些组合都不起作用。在尝试空密码时，我看到了以下内容：

The server requested password based authentication, but no password was provided

部分Db列表（也有template0和template1）：

postgres=# \l

  Name            |  Owner   | Encoding |   Collate   |    Ctype    |   Access privileges   
---------------------------+----------+----------+-------------+-------------+-----------------------
 postgres                  | postgres | UTF8     | en_US.UTF-8 | en_US.UTF-8 | 
 reportingdashboardproject | postgres | UTF8     | en_US.UTF-8 | en_US.UTF-8 | =Tc/postgres         +

用户列表：

postgres=# \du
                                   List of roles
 Role name |                         Attributes                         | Member of 
-----------+------------------------------------------------------------+-----------
 postgres  | Superuser, Create role, Create DB, Replication, Bypass RLS | {}
 repadmin  |                                                            | {}

我也尝试过显式授予超级用户特权：

postgres=# grant all privileges on database reportingdashboardproject to postgres;
GRANT

可能是某种sudo /权限问题吗？

postgres=# \q
could not save history to file "/opt/PostgreSQL/10/.psql_history": Permission denied

不确定接下来要解决的问题。感谢您的指导。
