Is that true for major and minor Pg versions? Last I checked it's only true for patch versions, OS updates, and instance size changes -- at least with multi-AZ. Perhaps it works for RDS clustering or Aurora?

Also wouldn't recommend the new blue-green switch over yet. It fails safe yet when it goes sideways it can take a while to clean up.

Hey @kosolam! Absolutely, we're excited about these developments too. It’s a team effort here at Ubicloud, and we're fortunate to have experienced folks from Heroku PG, Citusdata, Crunchy Bridge, and Azure CosmosDB for PostgreSQL. We all have firsthand experience with the challenges of self-hosting PG, and we're committed to making these features as user-friendly and robust as possible. Looking forward to bringing you HA and smooth upgrades soon!
