Hmmm...that's odd, since the query gets the sequence name through
a series of inner joins that go back go pg_class -- if the sequence
doesn't exist then where is the name coming from?  I did notice
that the query should add "AND attisdropped IS FALSE" to the join
with pg_attribute, but I don't see how that would affect this case.

Can you spot where the mistake is?  What does "\d tablename" show
for the table in question?
