Btree isn't a very useful index type for a vector, though. GIN, GIST, and the handful of new extensions optimizing for vector search are what you'd want (and don't have this limitation).
Aside, you can increase the size of tuples you can index in a postgresql btree by increasing the postgresql page size (requires a recompile and creating a new database instance).
