select with a function

Hi all, 
i need some help

i wanna do a select with a function call like this:

SELECT academico.aca_f_siguientecurso(      academico.aca_t_alumnocurso.ent_codigo,
academico.aca_t_alumnocurso.sec_codigo,     academico.aca_t_alumnocurso.ani_codigo,
academico.aca_t_alumnocurso.cic_codigo,     academico.aca_t_alumnocurso.esp_codigo,
academico.aca_t_alumnocurso.cur_codigo,     academico.aca_t_alumnocurso.cur_paralelo,
academico.aca_t_alumnocurso.est_codigo),     NULL as asp_codigo,      academico.aca_t_alumnocurso.alu_codigo FROM
academico.aca_t_alumnocursoWHERE academico.aca_t_alumnocurso.est_codigo IN
 
('AP', 'RP', 'RT');

the function academico.aca_f_siguientecurso returns a
custom type (a record).

ok, in the IRC AndrewSN told me this won't work in a
pre 8 pgsql, so i will need do it in a subselect but
the function has to be called once per row in
academico.aca_t_alumnocurso that matches the where.

<AndrewSN> but I don't know any easy way of doing that
for each row in a query.

any ideas?

regards,
Jaime Casanova
