Forunately I have a testing environment.

Let's find out!
Besides the 'default' zone there are three more old polices to remove:
'nostandby', 'nostandbykeys' and 'testshort'
non-matching kasp.xml:
root@metagross:~# ods-ksmutil policy purge
No zones on policy testshort; purging...
No keys to purge.
ERROR: error executing SQL - Cannot delete or update a parent row: a foreign
key constraint fails (`opendnssec`.`keypairs`, CONSTRAINT `keypairs_ibfk_2`

SQL failed: Cannot delete or update a parent row: a foreign key constraint
fails (`opendnssec`.`keypairs`, CONSTRAINT `keypairs_ibfk_2` FOREIGN KEY

Then I added <Policy name="default"></Policy> like entries but it's not
sufficient:

ods-kaspcheck returned an error, please check your policy
So I added full definitions of the old policies and 'ods-ksmutil update kasp'
is happy.

Let's try that again:
root@metagross:~# ods-ksmutil policy purge

sure? [y/N] y

I've also experienced the "Duplicate Keys" problem on this machine. The above
might be an
artifact of that. As there were dozens of zones to clean up I may have made a
few mistakes.
I realize the database has been corrupted. I still consider it an interesting
learning
and I assume you do so as well. However, don't stress yourself looking for an
answer.
I'm perfectly happy with trashing the entire installation if the situation
becomes hopeless.
