The sqlite3 library implicitly creates the database if the requested file doesn't exist.  I would like to be able to avoid that implicit creation.  (Actually, it would be enough to know whether I had created the database, but the underlying SQLite library doesn't seem to indicate that.)

The C code currently hard-codes the SQLite flag to create the database if it doesn't exist:

    rc = sqlite3_open_v2(database, &db,
                         SQLITE_OPEN_READWRITE | SQLITE_OPEN_CREATE |
                         (uri ? SQLITE_OPEN_URI : 0), NULL);

Could we make this an option, so the Python code could avoid implicit creation?
