You can't use REFERENCES on a column if the target primary key is made
up of more than one column; you have to use a FOREIGN KEY table
constraint:
create table matricula ( id_aluno char(15) references pessoa, id_curso int4 not null, -- I assume you
wantid_polo int2 not null, -- not null here local_prova varchar(50) not null, autorizado bool default
'f'not null, id_plano_pgto int2 references plano_pgto not null, data_matricula date default CURRENT_DATE not null,
primarykey(id_aluno,id_curso,id_polo), FOREIGN KEY (id_curso, id_polo REFERENCES curso_polo (id_curso,id_polo));
