In general, no. There are some exceptions, for example views using
EXCEPT I believe will not push conditions down. In 7.2.x, views using
any of the set ops (INTERSECT, UNION, EXCEPT) wouldn't push conditions
down. There are a few other such conditions, but for your view, I think
this isn't going to be an issue.
