At the moment it seems to be true for every pg_proc entry in template1.
AFAIK the attribute is not actually being looked at, anyway. I think
it used to be used to determine which functions needed to be executed in
a separate subprocess for safety reasons (ie, coredump of the function
wouldn't kill the backend) ... but that code's been gone for a long while.
