It did eventually finish, with the same result:

  efamroot@kat efam=# select chunk_id, chunk_seq, ctid, xmin, xmax, length(chunk_data) from pg_toast.pg_toast_10919630
wherechunk_id = 1698936148 order by 1,2;
 
    chunk_id  | chunk_seq |     ctid     |    xmin    | xmax | length 
  ------------+-----------+--------------+------------+------+--------
   1698936148 |         0 | (52888694,2) | 1511390221 |    0 |   1996
   1698936148 |         1 | (52888694,4) | 1511390221 |    0 |   1148
