Does this shed any light? pg_toast_6221538 is the relevant toast
table...

$ psql -c "set enable_indexscan=off; select chunk_seq,
length(chunk_data) from pg_toast.pg_toast_6221538 where chunk_id
= 19319495 order by chunk_seq;"
chunk_seq | length
-----------+--------
(0 rows)

$ psql -c "select chunk_seq, length(chunk_data) from
pg_toast.pg_toast_6221538 where chunk_id = 19319495 order by
chunk_seq;"
chunk_seq | length
-----------+--------
(0 rows)
