我无法连接到本地服务器上的自己的postgres数据库。我用谷歌搜索了一些类似的问题,并提出了本手册 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?
psql
,我该如何更改角色?
