Updated.
2) You didn't take into account the upgrade. Saved in Postgres with
this byte and try to load in version without this byte.
The PGSS_DUMP_FILE format is defined by PGSS_FILE_HEADER magic number
(the first four bytes in the dump file). Once they does not coinside
(when the file is being read) the statistics are not loaded from the
dump file and set to zero and the irrelevant dump file is skipped.
This is the actual behaviour implemented in the code.
