shutdown postgres under windows

Hello,

I have written a windows tray application which starts postgres under windows.

Now I want to shutdown postgres, when windows shutdowns my tray-application. In this case I cannot use the pg_ctl or
otherprograms. If windows is in shutdown mode, it does not allow to start a new program (like pg_ctl) to shutdown
postgres.
Sending a kill signal does not work under windows.

Can I shutdown postgres via a command per TCP/IP or direct with a sql-builtin command? The postgres docu describes only
theshutdown functions via pg_ctl. 

Thanks a lot for any hints,

Regards,
Thomas Wabner
