Hi, maybe filesystem-snapshots with wal's are your solution. There is a block-device replication-tool too. It's called drbd (http://www.drbd.org). I never tested/used it, but i heard it should be fine. I'm using rsync/xfs_freeze to make incremental filesystem-snapshots (incremental by hardlinks). This works fine/reliable for me :). best regards, Martin Am Freitag, den 01.07.2005, 15:51 +0200 schrieb Hannes Dorbath: > I need something that is able to replicate schema changes as well, so > Slony seems out of the game :/ > > pg_cluster? > mammoth postgresql? > db_mirror? > > What to use for a hot-standby box? > > Thanks in advance > > ---------------------------(end of broadcast)--------------------------- > TIP 4: Don't 'kill -9' the postmaster
