You wouldn't mind if I file a separate bug report regarding the last
problem (not related to the initial bug report)?
Now I can propose a minimal reproduction for it, that can ease testing
and choosing the most appropriate fix.
As to v4-0001-Fix-assert-failures-in-parallel-SERIALIZABLE-READ.patch
you posted before, I believe it fixes the issues as expected and may be
committed at least to allow for advanced testing.

Best regards,
Alexander
