PySide6 subclassing QSqlDatabase

I've run into an issue with PySide6 that I cannot subclass QSqlDatabase.

My biggest complaint about the QtSql system is that it does not throw exceptions when things go wrong. You have to manually check if things are really open or if there are any errors. So I want to subclass parts of it to automatically throw errors for me.

I asked this same question 5 years ago about PyQt5. That solution (from the venerable @eyllanesc) still works in PyQt6, but not PySide6. Here's a minimal example:

from PySide6.QtWidgets import (QApplication, QMainWindow, QTableView)
from PySide6.QtSql import (QSqlQuery, QSqlQueryModel, QSqlDatabase)
#from PyQt6.QtWidgets import (QApplication, QMainWindow, QTableView)
#from PyQt6.QtSql import (QSqlQuery, QSqlQueryModel, QSqlDatabase)
import sys

class ExceptionalDatabase(QSqlDatabase):
    @staticmethod
    def addDatabase(*args, **kwargs):
        db = QSqlDatabase.addDatabase(*args, **kwargs)
        db.__class__ = ExceptionalDatabase
        return db

    def open(self, user=None, pwd=None):
        if user is None:
            retval = super(ExceptionalDatabase, self).open()
        else:
            retval = super(ExceptionalDatabase, self).open(user=user, password=pwd)
        if retval == False:
            raise ValueError(self.lastError().text())
            
app = QApplication(sys.argv)

fid = open('example.db', 'w')
fid.close()

db = ExceptionalDatabase.addDatabase("QSQLITE")
db.setDatabaseName('example.db') # throws error that __init__ was not called
db.open()
if db.isOpen():
    print('database opened')
else:
    print('database did not open')

db.close()

sys.exit(app.exec())

It throws an error when I make the next call after addDatabase:

RuntimeError: 'init' method of object's base class (ExceptionalDatabase) not called.

If I try to explicitly call the __init__ function (db.__init__()), then it complains that I cannot call __init__ twice.
