Another option, if you're not confident of getting the postrm surgery right,
is to have your preinst script simply abort if it detects an upgrade from a
known-buggy version, instructing the admin to manually purge the package and
reinstall. This isn't a great option either because it means a dist-upgrade
will be interrupted, but it's more error-resistant than trying to, say, edit
a shell script with sed.
