Hey folks,
Anyone knows why the "sort_mem" parametr isn't by default in postgresql.conf file ? I had no idea it existed before, and we had some hudge queries running 1-2 minutes here, doing all sorts on disc, adding sort_mem = 512MB to config shortened that to 20s. These are run only ocasionaly, so the memory won't be always used - but helps in these few cases .
