This logger is used for troubleshooting sorts and other activities which are spilling to disk. If you use it at all, it's probably good to set it a something low like 1kB so that you know each query that spilled to disk, since any disk spill at all causes a dramatic slowdown in the query. Can be used to see if you need more work_mem, temp_mem or maintenance_work_mem.
