I believe sequences are implemented as a separate with one row that contains
the sequence parameters and state. It looks like somehow that one row has
been deleted and pg_dump expects it to be there.
Is this sequence being used by your program and is it functioning correctly?
Can you do a select nextval('person_sek')?
If you need the sequence and you know what its current value and other
parameters should be then I suggest droping and recreating the sequence.
