Well, it's not insane on its face. The rowtype of f in the first example
is necessarily a built-on-the-fly record, but in the second case using
the properties of the underlying named composite type is possible, and
consistent with what happens in 9.3 and earlier. (Not that I'm claiming
we were or are totally consistent ...)
