How about:
CREATE OR REPLACE FUNCTION public.uuid_write_(character varying)
RETURNS boolean
LANGUAGE plpgsql
AS $function$
BEGIN
INSERT INTO uuid_tbl_ ( uuid_col_ )
VALUES ( $1::uuid );
RETURN True;
END;
$function$
test(5432)aklaver=>select uuid_write_('34A94C40-453A-4A30-9404-128121E76570');
uuid_write_
