Yeah but the relevance drops precipitously as soon as you talk about only restarting the DB server. Planned downtime is less of a problem than unplanned downtime.

For example, at Google my caching strategies could be exported in production with only a few minor changes to the code. If we experienced data center downtime I could actually offload a hot cache to the other backing stores in round-robin configuration. The problem isn't when one database server gets taken down, it's when all the servers in the datacenter get taken down at once without any warning.
