Hmm.  Does the sequence still work (can you do SELECT nextval('person_sek'))?

Not sure why the dump attempt would be failing, and 6.3.2 is far enough
back that digging for bugs in it isn't very appealing.  I'd suggest just
looking for a work-around instead of a real solution.

You could probably just drop and recreate the sequence before running
pg_dump, being careful to set the new sequence's initial value to
whatever its current value is.
