I've updated this to include thoughts on how to upgrade postgres to 9.1. I'd like to do this soon (my next Monday, they're usually quiet? There will be a few minutes of total LAVA downtime).
Setting up streaming replication to enable us to cut over to the failover system is starting to seem like too much work for this. We could just rsync the postgres data across after shutting down LAVA on control and rsync it back again just before restart it after the upgrade.
The other option is to just take the downtime while the upgrade happens. It really shouldn't that long, but I can't really think of a way to gauge the potential cost ahead of time.
Team members, feel free to edit as appropriate. Anyone else with thoughts can add comments.
Still true!
Cheers, mwh
