Passing ROWTYPE parameter to EXECUTE

I am developing a function in Postgres which aims to recover for each record of a query the value of a result of a check contained in a set of functions. Only one of these functions will return the correct value. These functions have a common prefix ‘fn_condition_’ and receive an object of type ‘my_table’ as parameter.

As the number of functions that make the check is unknown, I decided to consult the Postgres catalog, from the table pg_catalog.pg_proc searching for functions with the prefix ‘fn_condicao_’ and dynamically execute them with EXECUTE.

My problem is the correct form to pass the parameter for EXECUTE.

create or replace function test_conditions()
returns void as 
$$
declare
    v_record my_table%rowtype;
    v_function pg_proc%rowtype;    
begin 
    set search_path = 'pg_catalog';

    for v_record in (select * from my_table where id in (1,2,3)) loop
        for v_function in (
            SELECT  p.proname
            FROM    pg_namespace n
            JOIN    pg_proc p
            ON      p.pronamespace = n.oid
            WHERE   n.nspname = 'operacional'
            and p.proname like ('fn_condition\_%')
            order by p.proname) 
        loop
         -- execute 'select ' || v_function.proname || '(' || v_record || ')';  -- ???
        end loop;
    end loop;
end;
$$ 
language plpgsql;

How to pass v_record properly in the commented EXECUTE command in the function above?

execute 'select ' || v_function.proname || '(' || v_record || ')';  -- ???

Example function:

create or replace function fn_condition_1(p_record my_table)
returns bigint as 
$$
begin 
    if ($1.atributo1 > $1.atributo2) then
        return 1;
    end if;
    return null;
end;
$$ 
language plpgsql;
