Then don't do that, or more accurately try looking at the setval not the
CREATE SEQUENCE.
The START value of a sequence isn't saved anywhere; it's merely the
initial value of the running counter, and so pg_dump cannot reliably
reconstruct it for you. I do not consider this a bug. pg_dump's
charter is to reproduce the database state when the script is reloaded,
and it does so.
