[GENERAL] Functions in postgres

[Tk421]

I've made some functions, an i want these functions to be used by a specified user, but i don't want this user can see the code of the functions. Does somebody knows how can i do this?       Sorry about my english, i'm spanish. V�ctor Robador Capel   An�lisis de Sistemas y Programaci�n   www.creativosdolmen.com
