[ADMIN] How to start postresql db server as a administrator on windows platform?

[Rich]

Hi there.. First, I'm a begginer to PostgreSQL. please, Don't fool me too much. ;-) As you see the title of this post, I'd like to know how to start postresql db server as a administrator of MS-windows os. (I'm trying not to run as a service.) Yes, I already know that according to the document, I have to be a unpriviliged user to run postresql db server on it. But, I have to run it as a administrator user. Isn't there any way to do that? If so, I can't help change DB system to a different kind of DBMS. Please, let me know how. Thank you very much in advance. Best Regards.
