So, I think that this is a really promising direction, but also that you should try very hard to try to get out from under this 6-byte PK limitation. That seems really ugly, and in practice it probably means your PK is probably going to be limited to int4, which is kind of sad since it leaves people using int8 or text PKs out in the cold.
My impression is that int4 is by far the most popular PK type. Even if the initial implementation is limited to that I think it'd have a lot of potential.
