Apart from the style of the prose, which is my subjective evaluation: This blog post is "a view from nowhere." Tiger Data is a company that sells postgres in some way (don't know, but it doesn't matter for the following): they could speak as themselves, and compare themselves to companies that sell other open source databases. Or they could showcase benchmarks _they ran_.

Them saying: "What you get: pgvectorscale uses the DiskANN algorithm (from Microsoft Research), achieving 28x lower p95 latency and 16x higher throughput than Pinecone at 99% recall" is marketing unless they give how you'd replicate those numbers.

Point being: this could have been written by an LLM, because it doesn't represent any work-done by Tiger Data.

For what it's worth, TigerData is the company that develops TimescaleDB, a very popular and performant time series database provided as a Postgres extension. I'm surprised that the fact that TigerData is behind it is not mentioned anywhere in the blog post. (Though, TimescaleDB is mentioned 14 times on the page).
The cynical take is: the AI doesn't know you-the-blog-post-author made TimescaleDB unless you tell it!
I don't understand your example: pgvectorscale was built and is maintained by Tiger Data
In terms of that example: they should link to how they got those numbers, and it should state the benchmark used, the machines used, what they controlled for etc.
