The update needs one for the case where the tuple stays in the same
partial table,
and the second for moving it to another table. The first is simple
(where old.x = new.x),
the second must delete the original and insert a new row into the view.
The view insert
rule handles the distribution (might be, that there are TODO's here, my
data stays in
place). The additional problem with the second rule is, that the
returned UPDATE tag (iirc)
does not return the correct number of rows (deleted + inserted rows, see
lengthy thread
about the return tag). Whether that is an actual problem will depend on
your apps.
