Actually, if you have a RAM disk, just change the $PGDATA/base/nnn/pgsql_tmp
subdirectory into a symlink to some temp directory on the RAM disk.
Should get you pretty much all the win with no need to move stuff around
afterwards.
You have to be sure the RAM disk is bigger than your biggest index though.
