Postgres server startup

[CM J <postgres.newbie@xxxxxxxxx>]

Hi,

         When logged in as administrator, i start the postgres server with the following command:

runas /user:postgres "D:\postgres_new\pgsql\bin\pg_ctl.exe start -D D:\postgres_new\pgsql\data"

           The problem is "runas" cmd is not script friendly as i can not pass the password as a cmd line argument.Is there any way i can start the postgres server using pg_ctl.exe while logged in as administrator without using "runas" ?? 

Thanks!
