I assume that SQLite returns an identifiable error if the database
doesn't exist when you try to open it, so you could just trap that error
and create it then:

        err = open_database(&handle, ...)
        if (err && err != database_not_found)
          return err;
        if (err)
          create_database(&handle, ...)

You probably could do something similar in get_mergeinfo, allowing you
to treat a non-existent database the same as an empty one.
