The CFBot finished, it failed in three environments
https://github.com/postgres/postgres-cfbot/actions/runs/35622455487/job/106409000471

All during the same test (recovery/027_stream_regress) that I pointed out
above to
be the best to detect issues. Coincidence or not it passed on MacOS (the
environment
I tested locally).

Am I being naive with my hopes to make this partially lock-free?
Is there any proof that such an algorithm doesn't exist for this particular
problem?

Kind regards,
