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

2、在数据库根目录下建立data目录：

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

3、去掉administrator对data目录的权限：

C:\Program Files\PostgreSQL\9.3>cacls data /e /t /r administrator

处理的目录: C:\Program Files\PostgreSQL\9.3\data
4、将data目录的权限赋给postgres用户：

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
5、用postgres用户打开cmd

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 postgresThe 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". Data page checksums are disabled. fixing permissions on existing directory ../data ... okcreating subdirectories ... okselecting default max_connections ... 100selecting default shared_buffers ... 128MBcreating configuration files ... okcreating template1 database in ../data/base/1 ... okinitializing pg_authid ... okinitializing dependencies ... okcreating system views ... okloading system objects' descriptions ... okcreating collations ... not supported on this platformcreating conversions ... okcreating dictionaries ... oksetting privileges on built-in objects ... okcreating information schema ... okloading PL/pgSQL server-side language ... okvacuuming database template1 ... okcopying template1 to template0 ... okcopying template1 to postgres ... oksyncing data to disk ... ok WARNING: enabling "trust" authentication for local connectionsYou 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 C:\Program Files\PostgreSQL\9.3\bin>

7、启动数据库，进入客户端：

C:\Program Files\PostgreSQL\9.3\bin>"pg_ctl" -D "../data" startserver starting C:\Program Files\PostgreSQL\9.3\bin>LOG: database system was shut down at 2014-09-18 10:19:54 HKTLOG: autovacuum launcher started C:\Program Files\PostgreSQL\9.3\bin>LOG: database system is ready to accept connections C:\Program Files\PostgreSQL\9.3\bin>psql.exepsql (9.3.5)Type "help" for help. postgres=#
