安装信息：

帐户已经存在。

请键入 NET HELPMSG 2224 以获得更多的帮助。

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the -A option the
next time you run initdb.

Success. You can now start the database server using:

    "E:\FRAMEW~1\POSTGR~1\bin\postgres" -D "E:/FRAMEW~1/POSTGR~1/data"
or
    "E:\FRAMEW~1\POSTGR~1\bin\pg_ctl" -D "E:/FRAMEW~1/POSTGR~1/data" -l logfile


然后我运行：

E:\framework\postgresql>"E:\FRAMEW~1\POSTGR~1\bin\postgres" -D "E:/FRAMEW~1/POST
GR~1/data"
Execution of PostgreSQL by a user with administrative permissions is not
permitted.
The server must be started under an unprivileged user ID to prevent
possible system security compromises.  See the documentation for
more information on how to properly start the server.


打开/data/pg_hba.conf配置文件：

# TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD

# IPv4 local connections:
host    all         all         127.0.0.1/32          trust
# IPv6 local connections:
#host    all         all         ::1/128               trust


应该没有问题呀，如何解决？或者指指账号如何写？

在LINUX下安装嘛。

    楼主明显是在WINDOWS下安装的哦。

Execution of PostgreSQL by a user with administrative permissions is not
permitted.

在windows下安装的时候默认也会创建一个postgres用户，你切换到postgres用户下执行就可以了

    我的意思是，建议到LINUX下安装postgresql, 这样对学习更有帮助。

如此啊。呵呵。
