Is anyone using Lifekeeper for Linux availability with Postgres?
If so, what are your thoughts on it? Work as advertised? Any dangerous gotchas?
I have a lot of customers using it. The latest version fixes the issue that Greg is talking about (as far as killing postgres) but it works very nicely. They even have added DRBD style replication with built-in failure detection / failover and switchback. It automates the sync and everything and can be monitored via a GUI.
