Hi, can we safely put the data from /var/lib/postgresql/8.4/main/ of server x to /var/lib/postgresql/8.3/main/ of server y, considering that the new target machine is running 8.3 whereas the old one ran 8.4 ?
No, a dump & restore is required (as stated in the release notes) You can also try pg_migrator. It was introduced with 8.4 and will upgrade the data "in-place" (i.e. without a dump and restore) Regards Thomas -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
