There is pgvectorscale from timescale which uses disk ann based data structure and has support for pre and post filtering.

I mention this towards the end of the post. it looks like a good solution, but it's not available on RDS

pgvectorscale is 100% open source

please ask your RDS rep to support it

we (tiger data) are also happy to help push that along if we can help

Is this something that can happen? We just ran into this limitation and I really want to keep using pgvectorscale... am exploring other solutions on EKS but RDS would be so much easier. From my reading it seems like this isn't something we can get done as a single AWS customer though.

		It is up to RDS. But there should be nothing stopping them. AFAIK they respond to customer interest.
