That's very likely to fail, and worse to do so silently, because 8.3 pg_dump doesn't know what's different about 8.4 system catalogs. I think your only real recourse in this situation is to do a plain dump from the 8.4 server (with 8.4 pg_dump) and then manually edit the dump script to remove any 8.4-only syntax. If your application isn't actually using any 8.4-only features this should be a pretty trivial matter. If it is, then of course you have some work to do. regards, tom lane -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
