Thanks, I got it. MultiInsertBuffer are created on the first non-zero
flush of tuples into the partition and isn't deleted from the buffers
list until the end of COPY. And on a subsequent flush in the case of
empty buffer we catch the error.
Your fix is correct, but I want to propose slightly different change
(see in attachment).
