I also tried "SHOW seq_page_cost" and that's 1.

Looking at
http://www.postgresql.org/docs/current/static/runtime-config-query.html#GUC-RANDOM-PAGE-COSTI
wonder if I should try reducing random_page_cost?

Something that might help when it comes to advice on performance tuning is
that this database is used only for analytics. It's essentially a partial
replication of a production (document-oriented) database. So a lot of
normal operations that might employ a series of sequential fetches may not
actually be the norm in my case. Rather, I'm doing a lot of counts on data
that is typically randomly distributed.

Thanks,
