wrong sequence value in dump file

CREATE SEQUENCE id_seq_test

INCREMENT BY 1

MINVALUE 1

MAXVALUE 1900000000000000000

START 100000000000

CACHE 1

NO CYCLE;

the cache is 1 then the problem seems not linked with the cache.

The value in the toc.dat file

000377c0: 0000 004b 0000 0053 454c 4543 5420 7067 5f63 6174 616c 6f67 2e73 6574 7661 6c28 2773 3033 3574 3030 2e69 645f 7365 715f 706c 6175 735f 7669 6f6c 272c 2031 3030  ...K...SELECT pg_catalog.setval('myschema.id_seq_test', 100

select last_value from id_seq_test;

┌──────────────┐
