Taking a step back, wouldn't it be better to increase "work_mem" and "temp_buffers" and set "temp_file_limit", so that temporary files are avoided whenever possible and temporary tables are cached? Then essentially you are using the same memory for the same purposes, but in a supported fashion. Yours, Laurenz Albe
