There are other approaches that could work too. For example, txtai can use Postgres as a data store and combine that with a vector index like Faiss or Hnswlib.

There are other approaches that could work too. For example, txtai can use Postgres as a data store and combine that with a vector index like Faiss or Hnswlib. In this case, you get the robustness of Postgres (which has been around a while) and Faiss (which is one of the most mature vector indexes). https://neuml.hashnode.dev/external-database-integration https://neuml.hashnode.dev/external-database-integration
