Please note this is not a perfect solution.
For example, the change of table A can't be detected using the "ctid".
If you update the link table with where clause including "name" field
and update the "name" and the "tiesize" field, the "tiesize" may not
be updated.....
It seems almost impossible for the driver to solve the problems perfectly.
Essentially it's a problem of the rule system.
