Strictly speaking, the sequence underlying nextval() has no idea what primary keys are or are not in use. It's just a transaction-ignoring counter that increases with each nextval() call. The only reason that you'd get duplicate key errors in this case are: 1. The sequence was reset to a different, lower value. 2. Rows were inserted that didn't use the sequence to select a primary key.
