Do I need to convert or port them to v8 in any way after I start up with a v8 postmaster? All major version upgrades require a dump and reload. You should read all the update notes for intermediate versions. You may also run into some bad-unicode data issues moving from 7.4 to 8.x. I would do a test run on a separate machine before committing to a conversion date (always a good idea IMO). -- Ghawar is dying ---(end of broadcast)--- TIP 4: Have you searched our list archives? http://archives.postgresql.org/

You will need to dump and reload, use the v8.2.5 pg_dump to connect to the v7.4.13 databases and restore. 3. There are specific behavior differences. The one that comes to mind most prominently is that float/double can no longer be ''. 4. Read the release notes from the docs 5. 8.2 is a completely different beast in terms of performance and configuration. Sincerely, Joshua D.

Do I need to “convert” or port them to v8 in any way after I start up with a v8 postmaster? Thanks Moving between major release versions requires that you do a dump/ restore using the new version's pg_dump and pg_restore apps.
