Could you build this?
Partial Basic async triggers in Postgres can be vibed, but building a production-grade background worker extension in Postgres for vectorization and chunking requires deep C extension expertise.
What it would actually take: A robust implementation typically runs as a Postgres background worker (written in C or Rust via pgx/pgrx) or an external queue listener (e.g., using LISTEN/NOTIFY with a Go daemon). The system handles chunking strategies, batching API calls or local ONNX inference, and transactional integrity alongside pgvector indexes without locking table writes. The hard part is managing database connection pools, memory pressure inside Postgres processes, and reliable failure retries.
