Do you plan on this also having point-in-time backups? That is the feature that I need in order to use Render.

fwiw - this is a key feature for many SOC2-esque certifications, so is likely a blocker for growing SaaS companies selling into enterprise.

Evan Arnold: We're prioritizing Point-In-Time Recovery and will roll it out before we ship HA.

My 2 cents - just want to make sure that we have the option to turn this feature off, or have it off by default. For applications that care about high data accuracy, I don't believe this can be done safely with Postgres

Just one data point: I was thinking about using Render or Heroku for our application, but the lack of HA pushed me towards AWS/GCP. It wasn't a total dealbreaker -- I could have used Render/Heroku with an AWS DB, but I decided to stick with a single provider.

(Heroku has HA, but it's async replication and will likely lose some data on failover: <https://devcenter.heroku.com/articles/heroku-postgres-ha>. I was very surprised to learn this!)
