I bet it's trying to find unused OIDs for toast pointers -- there are
only 2^32-1 of those available in any one toast table, and by the eighth
file of 500 million rows, you'd run out.

That seems to imply you can only insert 4Bn rows into a table with attached TOAST.  Am I misunderstanding something?
