Seems really really cool. Is this a full DB, as in they have to take PG source, put in tantivy and their sauce, compile, and distribute? Or is this an extension? If it's the latter, what's the point of putting DB at the end of the name?
Ok, all caught up now. Great work and best of luck!
When it comes to the business model: it seems an acqui-hire by Supabase/Neon/etc would be the best bet. It insures the team's focus is on the core product instead of the litany of things to figure out when creating a pg hosting service (payments, downtime, upgrades, customer support, ...) in this highly competitive and demanding market.
