It would seem that trying to hide code while using an open source system is just wrong. 8-)
That being said -- You would grant the user/group execute rights on the function, but no read rights on the system table that contains the function definition, pg_proc.
How is this user supposed to call the function? Does he have a cutomized application or does he have access to an SQL interface, such as Psql or PGAdmin?
Finally, I don't think you have to apologize for either bad English or for being Spanish, the native English speakers (and I only speak for myself here) appreciate the extra effort that non-English speaking people put in to allow the project to be fully internationalized. You should be proud of being Spanish, because even though there were a lot of bad points in Spanish history, Christopher Colombus did supposedly discover America, or something similar, and without that we wouldn't all be speaking English today.
