Hi Arne,
Thank you for the thorough and thoughtful response. As you suggested:

I will read through these sections carefully and come back with further
comments.
I genuinely admire the ambition of bringing this to WG3. Pushing a
Change Proposal to the SQL standard is no small undertaking, and I
respect the effort behind it. I hope the Stockholm meeting goes well.
On a personal note — I work on PostgreSQL upstream contributions myself,
and I have long been interested in the SQL standard as a living
document rather than a fixed reference. If I ever reach the point of
wanting to raise a small question or propose a correction based on
something I encounter in implementation work, would it be alright to
reach out to you?
Best regards,
Henson
