"Turbopuffer starts at $64 month with generous limits."

Yup, I think this here explains the popularity of pgvector. If $64/month seems like a lot to you, just use pgvector. If it seems cheap, then your usage is complex enough to want a proper vector DB.

It is most often not the $64. It is about being in sovereign control of your dataplane.

		Many people using pgvector have about 200 rows of data. Yesterday, I had a conversation with someone whether it's better to squeeze it all into the system prompt. Someone else argued that even with large context, it's difficult to fit 10k questions into a system prompt. So I think there's just this mismatch in usage.
