--- Comment #10 from Agustín Moyano <agustinmoyano at theke.io> ---
I agree there should be a consistent way to stop the upgrade process, and
specially one that will allow to resume from the place it broke, but I think we
should try to stop the upgrade process as little as possible.. 

meaning that for example if we add a FK on a nullable column, and there are
some values that don't exists in the foreign table, instead of killing the
process, we can copy the offending rows to some table we create, set the column
to null, add the restriction and raise a warning..
