Really cool. It'll be interesting to see how Multigres (by Supabase) shapes up compared to this. I think it's great to have more/better competitive hosted Postgres offerings.
This is especially interesting because Multigres is being led by Sugu Sougoumarane, one of the Vitess co-creators and Planetscale co-founders - so the two projects are growing from the same soil, so to speak.
