That's right. If preinst exits with nonzero, then dpkg unwinds by running postrm abort-upgrade or abort-install. I guess you'd have to handle those cases carefully to wind back the upgrade properly. Sounds messy to me. I asked at debian-devel this week and got a response which convinced me not too provide a "quit" option in the install scripts. At least in my case, I don't really need it.
