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

The article introduces Postgres.new, a service that runs a WASM build of Postgres (PGLite) in the browser, offering an in-browser Postgres sandbox with AI assistance. It leverages the 'single user mode' of Postgres and integrates with an LLM (GPT-4o) to provide an AI interface for database interaction. The technical innovation lies in the WASM implementation of Postgres, enabling it to run entirely within the browser, and the use of an LLM to manage and interact with the database.
