This made me wonder if storing the unadorned port number is really the best way. Suppose we did extend things so that we listen on different ports on different interfaces; how would this scheme work at all? I suspect it would be simpler to store both the interface address and the port, perhaps separated by :. You would keep it to one pair per line, so you'd get the IPv6 address/port separately from the IPv4 address, for example. And if you happen to have multiple addresses, you know exactly which ones you're listening on. To match a problem that has been discussed in the lists previously, suppose you have listen_addresses='localhost' and the resolver does funny things with that name (say you mess up /etc/hosts after starting). Things would be much simpler if you knew exactly what the resolver did at postmaster start time. > (I consider this feature so small that it doesn't deserve such a lengthy > discussion.
