I was thinking more about this idea, but IMHO, unless we send the key
toasted tuple from the publisher how is the subscriber supposed to
fetch it. Because that is the key value for finding the tuple on the
subscriber side and if we haven't sent the key value, how are we
supposed to find the tuple on the subscriber side?
