Really cool!

When should you use pgvector vs pgvector scale?

Is there any discussion about getting this added as a supported AWS RDS extensions?

pgvectorscale only makes pgvector better. The primary developer-facing improvement is the introduction of the StreamingDiskANN index type.

So we would recommend using both from the start. There is no cost (technical or financial) for doing so.

There is discussion about getting this added to AWS RDS (as well as other PostgreSQL providers), but too early to share anything.
