THE CASE AGAINST PGVECTOR

Summary from the TLDR Dev newsletter

While pgvector is a useful extension for bringing vector similarity search to Postgres, it's often oversimplified in online tutorials. There are still many challenges with running pgvector in production, including complex index management, query planning difficulties with filtering, and the hidden costs of real-time indexing. Existing blog posts often omit the operational realities and trade-offs involved, and for many teams, traditional vector databases are usually simpler.
