Every module is responsibile for protectiong own custom variables. Only
module knows if some variable needs protection. And after module
inicialisation module can call ArmorCustomVariable function. From this
moment only superuser can modify this custom variable. If it call
ResetPGVariable() function before then default value is protected. It's
question if test for superuser is necessery, I hope so it's usefull and I
have posibility write security definer function where I can safely modify
custom variables.
