BTW, you don't have to implement index from scratch. You can take one of many existing and modify towards Learned

Index contains many parts: scans, builds, vacuums, wal, opclasses etc. And simply adhering to API is a lot of work.
I'll be happy to help you to with formulating key differences and, probably, code of an extension.
