Integration for pgvecto.rs

[egorsmkv]

There's a different project for storing vectors:

https://github.com/tensorchord/pgvecto.rs

It'd nice to have integration as well.

That organization has https://github.com/tensorchord/vectorchord/

Probably, it can be also useful for someone.

Thank you very much!
In my opinion, it isn't the first priority now but we'll definitely implement it.
