Open-source cloud-native Postgres platform

Xata is a startup building a developer platform that wraps PostgreSQL (a popular open-source relational database) with cloud-native features like serverless scaling, built-in search, and a REST API — without needing a separate search engine or cache layer. The GitHub repo mentioned is their open-source offering, meaning developers can self-host the platform rather than using Xata's paid cloud service. This matters because it reflects a broader trend: traditional databases are being re-architected for serverless and edge computing, where auto-scaling, pay-per-use pricing, and integrated search/analytics are increasingly expected. Competitors include Neon (serverless Postgres), Supabase (open-source Firebase alternative), and PlanetScale (MySQL-compatible serverless DB).
