Postgres无法识别创建的用户

问题描述

我刚刚在Ubuntu 18.04上安装了Postgresql 10。我有postres默认的用户设置和密码。

我创建了一些用户和数据库，但出现此错误。我该如何通过？

:~$ sudo -i -u myUser01
sudo: unkNown user: myUser01
sudo: unable to initialize policy plugin

我确认它们存在：

                                      List of roles
    Role name    |                         Attributes                         | Member of 
-----------------+------------------------------------------------------------+-----------
 myUser01        | Superuser,Create role,Create DB                          | {}
 myUser02        | Superuser,Create DB                          | {}
 postgres        | Superuser,Create DB,Replication,Bypass RLS | {}



                                 List of databases
      Name       |  Owner   | Encoding | Collate |  Ctype  |   Access privileges   
-----------------+----------+----------+---------+---------+-----------------------
 myUser01        | postgres | UTF8     | C.UTF-8 | C.UTF-8 | 
 myUser02        | postgres | UTF8     | C.UTF-8 | C.UTF-8 | 
 postgres        | postgres | UTF8     | C.UTF-8 | C.UTF-8 | 
 template0       | postgres | UTF8     | C.UTF-8 | C.UTF-8 | =c/postgres          +
                 |          |          |         |         | postgres=CTc/postgres
 template1       | postgres | UTF8     | C.UTF-8 | C.UTF-8 | =c/postgres          +
                 |          |          |         |         | postgres=CTc/postgres

这是我的etc / postgresql / 10 / main / pg_hba.conf。请注意，如果这很重要，我将数据库管理员设置为md5，而不是peer。

# Database administrative login by Unix domain socket
local   all             postgres                                md5

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     peer
# IPv4 local connections:
host    all             all             127.0.0.1/32            md5
# IPv6 local connections:
host    all             all             ::1/128                 md5
# Allow replication connections from localhost,by a user with the
# replication privilege.
local   replication     all                                     peer
host    replication     all             127.0.0.1/32            md5
host    replication     all             ::1/128                 md5
