Обсуждение: pg_upgrade --link

hello to all,

i have tried pg_upgrade to upgrade from 8.4 to 9.0. the operation was
completed succesfully. i only have one question:

i did the procedure twice. once without the 'link (-k) option' and one with
it. obviously the attempt with the link option was much faster. but, what
does link mean here? symbolic link? i saw that after the procedure the old
'data' folder was there too, and i could delete it, so i guess the answer is
not symbolic link. so what does that link mean? thx in advance
