Some tips on how to backup / restore across versions. 1: pg assumes you're going from an old to a new version. i.e. 7.4 to 8.3 etc. Going the other way is not officially supported and you're on your own. 2: Run both versions of the db server at once. Use the pg_dump and pg_dumpall from the higher version, i.e. the destination db. So if you're going from 7.4 to 8.4, use 8.4's pg_dump to dump data. 3: use pg_dumpall --globals to get a list of users to import to the new database. 4: create tablespaces ahead of time if needed. so: pg_dumpall --globals -h pg74host -U postgres | psql -h pg84host -U postgres createdb -h pg84host dbname pg_dump -h pg74host dbname | psql -h pg84host dbname Should get mostly get you there. -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
