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).
that's cool and including the script is really great.
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.
From what I read the downtime would probably be less than 3 minutes. I
hate to waist developer *days* to save 3 minutes of uptime.
Team members, feel free to edit as appropriate. Anyone else with
thoughts can add comments.
Still true!
