Let's assume, for these purposes, that the person doing the tracing is
not the same as the person who created the Produced Work. Is that
What gives the person doing the tracing the right to trace? Is the
Database copyrighted? By tracing, are they copying a copyrightable
portion of the Database? By tracing, are they extracting a
substantial portion of the Database? If so, what gives them
permission to do that?

The person creating the Produced Work is specifically prohibited from
sublicensing the Database. So any license granted by the producer of
the Produced Work is not a license on the underlying Database itself.

You have permission to license the produced work, not the underlying
database. See 4.8.
Can you publish a Produced Work under CC-BY-SA? Personally, I don't
think you meaningfully can. The only semi-reasonable argument I've
heard that you can, came from an ODbL lawyer who basically said, yes,
you can publish a Produced Work under CC-BY-SA, because CC-BY-SA
doesn't apply to databases anyway.
I think Ed Avis is right on that one, though. "It's allowed to make
map renderings, but if you want to produce a truly CC-licensed or
public domain one you can't. (This refers to the no-tracing
restrictions; an attribution requirement is more reasonable.)"
