I'm informed that the last statement of a function that returns void cannot be
a SELECT. How else is one supposed to call another function which also
returns void?
E.g.,
CREATE FUNCTION foo (a int, b int) RETURNS void
LANGUAGE plpgsql
AS $$ do important things $$;
CREATE FUNCTION foo (a int) RETURNS void
LANGUAGE sql
AS $$ SELECT foo($1, default-value); $$;

PERFORM works only in plpgsql, Peter wrote a pl/sql-function...

Hmm, seems like the best answer is to rejigger the order of the tests in
check_sql_fn_retval. I think that logic was designed before we had an
idea of VOID-returning functions.
