So looks like you're falling back on one INSERT per row for this case.
Given that this function is meant to be doing 'dump_inserts_multiple'
INSERTs per row, I think the comment should give some details of why
we can't do multi-inserts, and explain the reason for it. "we're done"
is just not enough detail.
I've not looked at the rest of the patch.
