It isn't, and isn't likely to become so, at least not for C code. We generally think of the C code as being at a lower level than SQL. If we rename a global variable that underlies a GUC variable, it's probably because we *want* to break any C code that references it --- perhaps the semantics are changing, or something like that. regards, tom lane
