I agree. Maybe something along the lines of "temp_file_limit"?
Also, once you free yourself from the analogy to work_mem, you could
adopt some more natural unit than KB. I'd think MB would be a practical
unit size, and would avoid (at least for the near term) the need to make
the parameter a float.
