Maybe exactly. I rememberd the discussion.
So the issue there is neither EndRecPtr and ReadRecPtr always points
to the current read LSN. The first proposal from Nathen was to use
currRecPtr but it was a private member. But after discussion, it
seems to me it is (at least now) exactly what we need here so if we
ofccially exposed the member the problem would be blown away. Do you
want to conitnue that?
Otherwise, I think we need to add a comment there about the known
issue.
regards.
