无法在 postgresql 中创建用户

Question

我在 Windows 的 powershell、命令提示符和 ubuntu 上进行了尝试：

postgres=# CREATE USER sally WITH PASSWORD 'secret';
CREATE ROLE
postgres=# \du
                                   List of roles
 Role name |                         Attributes                         | Member of
-----------+------------------------------------------------------------+-----------
 postgres  | Superuser, Create role, Create DB, Replication, Bypass RLS | {}
 sally     |                                                            | {}
postgres=# \q
> psql -U sally
Password for user sally:
psql: error: could not connect to server: FATAL:  password authentication failed for user "sally"

如果我写 psql 或 $ sudo su - postgres（在 ubuntu 中）

它会询问我的 Windows 用户名（恭敬地）：

Password for user xyz:

[sudo] password for xyz:

这是我的pg_hba.conf

...
# local      DATABASE  USER  METHOD  [OPTIONS]
# host       DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
# hostssl    DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
# hostnossl  DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
#
...
# TYPE  DATABASE        USER            ADDRESS                 METHOD

# 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.
host    replication     all             127.0.0.1/32            md5
host    replication     all             ::1/128                 md5

Answer 1

在连接时添加-h 127.0.0.1，或在pg_hba.conf 中添加local 规则。

此外，如果它与用户名不同，请指定所需的数据库名称：-d <dbname>。
