Always a good idea to do this kind of thing inside a BEGIN block ;-) As far as the system functions are concerned, you can just set the proacl column to NULL (ie, default) and that'll be fine for everything except the character conversion functions. As far as user-defined functions are concerned, NULL probably works for most of them too, but you would want to consult a recent backup to see if any were not like that. regards, tom lane
