> Timescale lately released the pgvector extension, that turns your PostgreSQL into a vector database.

I don't think this is accurate and smells like an LLM hallucination to me.

From the Timescale/Tiger Data _pgvectorscale_ project's README:

> pgvectorscale builds on pgvector with higher performance embedding search and cost-efficient storage for AI applications.

I think this is where the confusion originates. I believe pgvector is primarily Andrew Kane (@ankane) and a cadre of OSS contributors.

As an aside, I've used Timescale/Tiger Data products and was very happy with them and their support. Their team was very engaged and responsive to all of our questions. They also fixed a pretty gnarly indexing bug I uncovered in pgvectorscale in an impressively short amount of time.
