环境：win7 64 sp1
PG：9.3.5

1、创建用户postgres,密码同样是postgres:

net user postgres postgres /add

C:\Program Files\PostgreSQL\9.3>md data

C:\Program Files\PostgreSQL\9.3>cacls data /e /t /r administrator
处理的目录: C:\Program Files\PostgreSQL\9.3\data

C:\Program Files\PostgreSQL\9.3>cacls data /e /t /g postgres:C
处理的目录: C:\Program Files\PostgreSQL\9.3\data

C:\Program Files\PostgreSQL\9.3>runas /user:postgres cmd.exe
输入 postgres 的密码:
试图将 cmd.exe 作为用户 "SURE-PC\postgres" 启动...

6、进行初始化，初始化用户为postgres,字符集为utf8，locale为C：

C:\Program Files\PostgreSQL\9.3\bin>initdb.exe -D ../data -E utf8 --locale C -U
 postgres
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locale "C".
The default text search configuration will be set to "english".

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

Success. You can now start the database server using:

    "postgres" -D "../data"
or
    "pg_ctl" -D "../data" -l logfile start
