I vote for "not" --- doesn't seem like there'll be much external
code affected, and we make comparably-sized API breaks all the time.

As a matter of style, I wonder if it'd be better to have these
functions write into a caller-supplied variable.  That seems more
in keeping with most other places in Postgres, and it would save
a copying step in cases where the caller needs the result on the
heap.  I realize that returning structs has been in C for decades,
but that doesn't mean I want some of our APIs doing it one way and
some the other.
