Sequences are non-transactional, so pg_dump might well capture a higher
value of the sequence counter than is reflected in any table row, but
there are numerous other ways by which a gap can appear in the set of
sequence values. That's not a bug. If you've got real discrepancies
in pg_dump's output, a lot of us would like to know about 'em.
