This isn't particularly surprising: the planner will feel free to push
that WHERE condition down as far as it can. Probably there is some
aspect of the view definition that prevented such an optimization in
prior versions but doesn't deter 8.3. You didn't show us the view
though, nor any EXPLAIN output ...
