Thanks for the reproducible test case.  This bisects down to this commit,

commit 277cb789836b5ddf81aabb80c2058268c70e2f36

    Don't reuse slots between root and partition in ON CONFLICT ... UPDATE.

I was a little surprised it was this particular commit, because your test
doesn't use partitioning.

I don't know how to investigate the issue further, so I'm copying Andres
and will add it to the open issues page.

Cheers,
