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.
