PostgreSQL:不允许角色登录

Question

我无法在本地服务器上连接到我自己的postgres数据库.我搜索了一些类似的问题并提出了这本手册 https://help.ubuntu.com/stable/serverguide/postgresql.html

所以:

pg_hba.conf 说:

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     trust
# IPv4 local connections:
host    all             all             127.0.0.1/32            md5
# IPv6 local connections:
host    all             all             ::1/128                 trust

然后我创建一个用户并为其分配密码:

postgres=# create role asunotest;
CREATE ROLE
postgres=# alter role asunotest with encrypted password '1234';
ALTER ROLE

但它不允许我进入:

-bash-4.2$ psql -h 127.0.0.1 -U asunotest
Password for user asunotest: 1234
psql: FATAL:  role "asunotest" is not permitted to log in

可能是什么问题呢？
