It seems like _sqlite3 heap types support regular instantiation and so that no
change is needed.
* sqlite3.Cache
{Py_tp_new, PyType_GenericNew},
* sqlite3.Connection
{Py_tp_new, PyType_GenericNew},
{Py_tp_init, pysqlite_connection_init},
* sqlite3.Cursor
{Py_tp_new, PyType_GenericNew},
{Py_tp_init, pysqlite_cursor_init},
* sqlite3.Node
{Py_tp_new, PyType_GenericNew},
* sqlite3.Row
{Py_tp_new, pysqlite_row_new},
* sqlite3.Statement
{Py_tp_new, PyType_GenericNew},
$ ./python
Python 3.10.0a7+
>>> import _sqlite3
>>> conn=_sqlite3.Connection(":memory:")
>>> type(conn)()
TypeError: function missing required argument 'database' (pos 1)
>>> conn2 = type(conn)(":memory:")
>>> list(conn.execute("SELECT 1;"))
[(1,)]
>>> list(conn2.execute("SELECT 1;"))
[(1,)]
