The problem of pg_upgrade is that it needed to hold two set of databases data in the server. This is not be desirable (very slow) or possible (space limitation) for database with huge data. For example, if the old version is already using over 50% of the mount point. The new database may not have enough disk space for the upgrading.
I think if you use the --link parameter, you don't need additional disk space (or only little). -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
