That is the conclusion I have come to.

When a difficult question comes up, you end up having to know the exact
requirements and behaviour of the underlying database anyway. Then once
you know what sequence of commands you need to be issued, you have to
figure out how to persuade the ORM to do it (and not something similar
but subtly wrong). At this stage it's getting in your way.
