ODB only supports auto-generated ids for integers (by using the
corresponding underlying database's functionality). One way to
achieve the same for a string would be to generate UUIDs on the
application side. For example, you could use the Boost.Uuid
library. In that case it might even make sense to use
boost::uuids::uuid type instead of std::string (Section 23.6 in
the ODB manual).
