Fwiw here's the perl one-liner I used to tune sort_mem recently,
(run in the $PGDATA/base directory):
perl -e 'while (sleep(1)) {if ($s = -s <pgsql_tmp/*>) { if ($s > $m) { $m = $s; print
"$s\n"; } } }'
When doing this I had precisely the same thought about having Postgres print
out the disk space usage for sorts.
