impl FromSqlRow<Timestamptz, Pg> for NaiveDateTime

It looks like I had forgotten a handful of impls when I added the
feature. I intentionally excluded several types from the `FromSql` side,
but it makes sense for us to allow `NaiveDateTime`, and b6b56c97 makes
it sound like I had intended to do so in that commit.

Fixes #539.
