I was more thinking about the problems like a database upgrade requiring 
changes to e.g. the system tables of the database handled in the 
{pre,post}inst scripts. It even becomes more tricky since a postinst 
script might make changes to both /usr and such required actions.

These issues which require auditing of all packages are the real issue.
