I'm sorry. In fact, I was not so carefull with my analisis and the
example I provided you was not exactly like the real problem.
First, I have failed to use the same type in the columns (integer in one
relation, varchar in the other). I think this was the major problem. To
make the example more realistic:
user_operations (
        user_id    integer,
        user_name  varchar,
        user_operation varchar)
CREATE TABLE users (
        user_id         varchar,
        user_name       varchar);
the column user_id from the relation users was with the wrong type
(varchar). I changed it to integer (as user_operations), and the INSERT
works well.
