I've just noticed this. Something is not right here. Look at the crazy cost estimation for the second query. It looks to me like enable_indexscan, enable_tidscan, enable_sort, enable_nestloop, enable_mergejoin or enable_hashjoin have been set to false. Looking at the source, thats the only way I can see that such large numbers can be produced.
