Yes, we could add a test that tracks

You mean like in a TODO: block in the test?

In this case, yes, it seem the consensus (though it's early to call it)
is SHAKE256.

Thank you for posting it there. If I understand correctly, the resolution
should be to use internal hash algorithms — in this case, SHAKE.
Now, the question is whether to wait for the implementation of a public API
to make the change as general as possible, or to try implementing it on the
PG side?
I posted (including your attachment, by accident, since at first I was
going to forward your post) about this to the IETF TLS WG mailing list.

Looking more carefully, ML-DSA

Wow. Thanks Nico

Thanks, I'm able to reproduce your problem with the error you have,
after generating the certs.

Hi,
Thank you for the detailed feedback. Let me address your points:
Test Case

I have prepared a test case following the pattern from commit 9244c11afe23
(RSA-PSS fix).
Regarding the Hash Algorithm

You are correct that, according to RFC 5929, we should i

Hi hackers,
While working on testing post-quantum cryptography integration in my
system, I discovered that PostgreSQL has an issue with channel binding when
using ML-DSA cryptographic algorithms.
The problem is caused by a difference between the currently used algorithms
and post-quantum ones. Fo
