Work-mem is kind of tricky because the right setting depends on how much ram
your machine has, is the machine dedicated to postgres, and how many
simultaneous connections you have.  If this is a test server, and not used
in production, you could just play around with the setting and see if your
query gets any faster.

Here are the docs on work mem
