Comment (by strk):

 As I'm getting these WARNINGs multiple times during upgrades (we have
 multiple GUCs now) I looked at the issue again and wondering... why didn't
 we just opt for undefining the old GUC and replace with the new ? Apart
 from the difficulty to tell what's old and what's new, in case both
 libraries survive. Actually I'm thinking we should include lib version in
 those WARNINGs so at least we know if the complaining one is the *new* or
 the old, because it is still possible that the old library is loaded
 *after* the new library, right ?
