Обсуждение: pg_dump, pg_restore from 9.2 on 8.4 server
Hi All,
I have a 8.4 server and I'd like to use --section parameter of pg_dump and pg_restore, which is available only in 9.2.2013/7/3 Jiří Hlinka <jiri.hlinka@gmail.com>: > Hi All, > > I have a 8.4 server and I'd like to use --section parameter of pg_dump and > pg_restore, which is available only in 9.2. > > 1.

Does the --section parameter need support on a server side, or is it just > the client tool feature? It's a pg_dump feature; it seems to work fine using 9.3b2's dump against an 8.3 database.

If you use a 9.2 pg_dump, you'll be garanteed to restore it on 9.2 and upper, not lower (not 8.4 for instance). -- Guillaume http://blog.guillaume.lelarge.info http://www.dalibo.com
