The Catbench Vector Search Demo showcases the capabilities of using Postgres SQL for vector search with a focus on measuring throughput and latency. This development is crucial as there is a lack of effective benchmarks for vector search that can simulate real-world scenarios. However, some industry experts suggest that referring to it as a 'bench' may be misleading, as its functionality is more aligned with a demonstration of the pgvector application rather than a comprehensive benchmarking tool.
