Plans to adopt PostgreSQL 18 parallel I/O for index page reads?

Hello,

I’m curious whether there are any plans to integrate PostgreSQL 18’s new asynchronous/parallel I/O features (e.g., io_method, io_workers, io_max_concurrency) into index access methods. In particular, will index page reads (such as those in pgvector’s IVF/HNSW search) be able to take advantage of the new parallel read infrastructure, rather than relying solely on synchronous ReadBuffer calls?

Thanks!
