I raised a question in my original post that I haven't seen discussed:

Is failing to change the sequence ownership a bug in pg_dump, or
should changing a table's ownership also change the ownership of
implicitly-created sequences?  That seems the most reasonable
behavior to me: I'd expect that the cases where you wouldn't want
this to happen would be the exception, not the rule.  DROP TABLE
cascades to implictly-created sequences -- why shouldn't ALTER TABLE
OWNER TO cascade as well?
