It sounds to me that the only solution to my case is
executing

DELETE FROM referenced_table

and

INSERT INTO referencing_table

in seperate transactions. Please correct me if I am wrong.

I also feel it might be a good idea to include an example
like the one in my previous message in the documentation so
that this question hopefully will not be asked repeatedly.
