They are conffiles, at least quite often. /etc/cron.d/postgresql is a
conffile for postgresql. In a worst case scenario, the new cron file
could be run before the package is ready to handle it and it could
break the package. cron would die, but postgresql, for example, might
die.
However, your example may be easier to understand.
