That was my initial reaction to this suggestion. But then I realised 
that it might well make sense to have a separate connection-limited 
superuser for Slony purposes (or any other special purpose) alongside an 
unlimited superuser. If we were restricted to having just one superuser 
I would be much more inclined to agree with you.  Perhaps if this 
suggestion were to be adopted it could be argued that the superuser 
reserved connection slots should be kept only for superusers that are 
not connection-limited.
