I think this doesn't exist. Paradoxically, I think that makes sense:
a failure in a {pre,post}-{install,remove} script indicates an
exceptional situation the packagers haven't taken in account, thus
one they could't provide for; thus the intervention of a sysadmin
with knowledge seems appropriate.
A force argument for that seems like a dangerous trap. Better having
folks come here, as you did (I myself did, a while back :-)
