  I am not sure, if it can ever enter into this flow without resowner as
mentioned in jeff comments 
  for session level locks. If it cannot enter then it is okay.

  In you previous mail you agreed with level as ERROR for elog message in
function ResourceOwnerForgetLock(..) function,   
  but in your modification you have used PANIC, is there any specific reason
for it.
