Well, I don't see why it has to be that way. We can maybe avoid macros a
little by doing

class Users
     BOOST_DECLARE_SQL_COLUMNS( "column_age", age, "column_role", role );

     boost::sql::variable<int> age;
     boost::sql::nullable_variable<std::string> role;

AFAICT, the only thing you have to debug is mismatch in the column/table
names. But that should be easy to detect at run-time, thus
easy to catch in unit-tests.
