Why is it not reliable?  It looks to me like the perfect filter -
particularly as you change it on upgrades.  We would only offer an
upgradeprovision if it is less than alpah13 (or whatever you recommend
as a cut-off).

I agree in future we could populate the DB with more info, but we need
to work with what we have at the moment. 

The only other way to do this is to look for specific errors as
tell-tale indications that the DB is an old, incorrect provision.  Do
you have any ideas which errors we could look for.  Then, depending on
what they are, we can either teach dbcheck about them, or offer an
upgradeprovision if (even with it's known issues) it is the best option
