What? I had a cluster over 3TB and it was offline for only 10 minutes doing a major version upgrade using pg_upgrade's --link option. Of course, that was with minimal statistics -- just enough to keep from getting truly stupid plans. If it takes *days* to run pg_upgrade on a 1TB cluster either you have an insane number of database objects or you are not taking advantage of the available features. -- Kevin Grittner EDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
