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 -- View this message in context: http://postgresql.1045698.n5.nabble.com/pg-upgrade-link-tp4799801p4799801.html Sent from the PostgreSQL - admin mailing list archive at Nabble.com. -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
