Is possible to use Prepare/Execute inside a function?

Hello, I'm having problems with a function after the postgres server has
been upgraded to 8.3.10 (I used 8.3.7). I did some testing and found
some strange situations.
------------------------------------------------------------------------------------------------------------
-- not work with the direct call function (worked before the upgrade)
select f_rodar_reportagem(44359, 193097);

-- not work with the call by the trigger (a trigger calls a function and
it calls f_rodar_reportagem using select and worked before the upgrade)
update repesportesmt set
estado = '1'
where idrepesportesmt = 44359;

-- WORK using Prepare/Execute
prepare rodar(int, int) as select f_rodar_reportagem($1, $2);
execute rodar(44359, 193097);
-------------------------------------------------------------------------------------------------------------

I do not understand why not working after upgrade, but worked with
prepare/execute, so I tried to use inside a function but did not work.

-- got error in this line on params
prepare rodar(int, int) as select f_rodar_reportagem($1, $2);
