Actually, what I'd suggest is just some code to serialize and
deserialize tuples and transmit 'em via the existing NOTIFY payload
facility.  I agree that presenting it as some functions would be a lot
less work than inventing bespoke syntax, but what you sketched still
involves writing a lot of communications infrastructure from scratch,
and I'm not sure it's worth doing that.
