Actually, a config file in Debian is replaced if it has _not_ been 
changed locally, and it _has_ been changed upstream. If it has been 
changed on both sides, you get prompted. If the new package is just a 
security update, which in most cases means changes to the binaries and 
not to the default config, then it will just install without prompts, 
and not touch your config files. If it's an entirely new version, then 
the desire to just upgrade silently is sort of inappropriate anyway - 
you will need some preparation.
