This is not EXPLAIN ANALYZE output. Also, the rowcount estimates
seem far enough off in the other query to make me wonder how long
it's been since you ANALYZEd the tables...
More generally, though, I don't see anything particularly wrong
with this query plan. You're selecting enough of the table that
an indexscan isn't necessarily a good plan.
