Right, they have. But PostgreSQL doesn't and so PL/pgSQL can't. PL/pgSQL cannot do any thing that a C function in PostgreSQL cannot do. The PL handler is written in C and that is what the executor calls instead of the compiled function. From the backends point of view, a PL handler is just one C function with a bunch of personalities.
