Thank you, Amit!

I'd like to note that the culprit is exactly pg_largeobject as coded in
dumpDatabase():
     /*
      * pg_largeobject comes from the old system intact, so set its
      * relfrozenxids, relminmxids and relfilenode.
      */
     if (dopt->binary_upgrade)
...
         appendPQExpBufferStr(loOutQry,
                              "TRUNCATE pg_catalog.pg_largeobject;\n");

I see no other TRUNCATEs (or similar logic) around, so I would specify the
table name in the comments. Though maybe I'm missing something...

Best regards,
Alexander
