Wow, that's pretty bizarre. I'm not too concerned about trying to
work out how 6.5 could get into a state like that --- but if you can
reproduce it on a newer release, let us know ;-)

Meanwhile, your best bet is to try to drop the sequence so pg_dump
won't spit up. Evidently you are missing the tuple data type that
normally goes with a relation (including sequence relations).
Fortunately, delete isn't real picky about *what* type it drops,
it just wants to find one with the right name. So try

create type reporters_idnum_seq(input = int4in, output = int4out);

and then see if you can drop the sequence.
