The sort steps seem slower than they ought to be. I suspect you ought
to raise sort_mem ... try 10MB instead of 1MB. Also, if you are running
in a locale other than C and don't have a good reason for doing so, it
would be worth trying C locale instead.
The results with enable_seqscan off also suggest that random_page_cost
may be too high for your environment.
BTW, the schema you posted does not match these plans --- there are
indexes referenced in the plans that do not appear in the schema.
