To clarify a bit, there may exist differences in the ordering of columns, either between the parent and its partitions or between different partitions. For example, while parent's rowtype is (a int, b char, c float), a partition's may be (b char, a int, c float), and yet another partition may have (c float, a int, b char). If some user code happens to depend on the ordering of columns, selecting from the parent and selecting from a partition directly may return the same result but in different formats.
