Show HN: PgCortex – AI enrichment per Postgres row, zero transaction blocking

PgCortex represents an innovative approach to integrating local LLM inference into data pipelines. By embedding AI enrichment directly at the database layer, it solves a fundamental problem: how to scale LLM operations across millions of records without blocking transactions or managing complex external queues.

The zero-transaction-blocking design is particularly important for production systems. Traditional approaches require exporting data, running inference, and reimporting results—causing locks and operational complexity. PgCortex likely uses background workers or asynchronous processes to enrich rows in-place, maintaining database availability throughout the operation.

For teams deploying local LLMs at scale, PgCortex opens new architectural possibilities. You can now run inference-heavy operations (classification, summarization, embedding generation) directly within your database infrastructure, leveraging local models for privacy and cost efficiency while maintaining transactional integrity and performance.
