Bug #678: delete rules false report

The lower the number the more severe it is.

Short Description
delete rules false report

Long Description
I've just upgraded my database to postgre 7.2.1 from version 7.0.1.

I noticed that ON DELETE rules for views reports always DELETE 0 where it should report DELETE 1.

For example:
I type,
orders_db=# delete from view_orders_source where orders_id = 6533;
and postgre says,
orders_db=# DELETE 0
although the row has deleted succesfully.

When I try this on postgre 7.0.1 the reply is ok (DELETE 1).
