The ctid of the target table of the rule's last statement should be referenced.
For example, in your case the command

	UPDATE "public"."vhusband"
	SET    "name"=E'hello44',"tiesize"=52
	WHERE  "id" = 10
	AND    "ctid" = E'(0,47)'

is issued by MS Access.
The where condition "id" = 10 AND "ctid" = E'(0,47)' is added to
each statment in the rule when the command is executed.
So it's very siginificant that the contents of "id" and "ctid"
are not changed until the last statement is called.
Please note that the ctid field is modified autmatically when
the table is updated.
