I think the problem here is that "t.*" gets expanded into a list of
all of t's columns, just as would happen in a SELECT's output list.
Try
returning merge_action(), t
It might also be necessary to declare the target variable
"m_new_data" as being of type my_table rather than generic
"record"; not sure about that.
