How can I run an external program from a stored procedure?

Greetings!

I'm running PostgreSQL 8.4 on MS Windows Server 2003.

Assume I have a program named FlashLightAndSoundHorn.exe. In my
database, there is a table that is read by some other program. Records
in that table have a timestamp, so I can tell how long they've been
waiting. I want a stored procedure that checks to see if a record has
been waiting too long, and if it does, then it will run
FlashLightAndSoundHorn.exe. How do I run that program from inside a
stored procedure?

Thanks very much!
