Thanks Jim and Tom.  At least now I've got a direction to head in.  I
think for now I'll probably reduce work_mem as a stop-gap measure to get
the query running again.  This will buy me some time to redesign it.
I'll probably separate out each sub query and store the results in a
table (would a temp table be a good solution here?) before I pull it all
together with the final query.

Yes, it would. It's also possible that you could structure the query better, to reduce the amount of concurrent sorting/hashing going on.
