postgres.new: In-browser Postgres with an AI interface

Introducing postgres.new, an in-browser Postgres sandbox with AI assistance. It allows the creation and management of Postgres databases directly in the browser using PGlite, a WASM version of Postgres. Key features include drag-and-drop CSV import, report generation, chart creation, and database diagram construction. The platform leverages a large language model for autonomous database operations, and it supports semantic search with pgvector. Future enhancements include deploying databases to S3 and supporting more file types.
