There's something interesting in the original report:

So pg_dump found a pg_depend entry linking that sequence to some table
named transaction_backup, not transaction. That explains why
transaction isn't being dumped using a SERIAL keyword --- it's not
linked to this sequence. But how things got this way is not apparent
from the stated facts.
One possibility is that Jeffrey is getting bit by this bug or
something related:

There are links to some other known serial-sequence problems in 8.1
in this message:

None of those reports seem to exactly match the described behavior, but
anyway I'd bet a good deal that either the table or the sequence has
been altered in some way since they were created. Given that Jeffrey
says all his sequences fail the same way, it must've been something
he did to all his tables/sequences ...
