This seems to be a serious issue. But hopefully the need for the
predependency will dissolve in the future anyway because we plan to
change PostgreSQL packaging to a system which can have multiple major
versions installed in parallel, so there's no need for backing up in
the preinst any more.

Thanks and have a nice day!
