Related #51.

@pcisar Looks like there is still a problem with this. The current code:

            with contextlib.suppress:
                self._att.detach()

causes:

Exception ignored in: <function Connection.__del__ at 0x000001F220A48400>
Traceback (most recent call last):
  File "C:\Temp\dwdb-workspace\dwdb\.venv\Lib\site-packages\firebird\driver\core.py", line 1802, in __del__
    with contextlib.suppress:
TypeError: 'ABCMeta' object does not support the context manager protocol

It needs to be adjusted to:

            with contextlib.suppress(DatabaseError):
                self._att.detach()

This correctly suppresses the exception and doesn't display the Exception ignored message.
