I am not against giving examples in the docs to make the topic easy to
understand but in this particular case, I am not sure if additional
examples are useful. You already gave one example in the beginning:
"For example, note below that subscriber table generated column value
comes from the subscriber column's calculation." the remaining text is
clear enough to understand the feature.

If you still want to make a case for additional examples, divide this
patch into two parts. The first part without examples could be part of
this thread and I can commit that. Then you can start a separate
thread just for the examples and then we can see what others think and
make a decision based on that.
