Forgot to say. A low value of work_mem will make it more suitable for
PostgreSQL to use temp files if numerous sorting jobs need quite a good
amount o memory.

You might as well try different values of work_mem to see what happens
(watch out for large values of work_mem), or rethink your query all
together.

Cheers,
