[briffle]

It takes us a few months to upgrade, with planning, testing, co-ordinating downtime, etc. We upgrade every other year, to keep us from falling too far back.

Very excited for this year, as we'll be using logical replication to migrate, which should make this much less risky. (since the old systems are untouched).

In the past, we used pg_upgrade for in place upgrades, and even though we took snapshots before, still seemed a bit stressfull when it happened.
