Yes, this will break autovacuum, because it won't have any way to find out
what it should vacuum. The cause probably is a DNS issue: "localhost"
isn't resolving to anything sensible. "dig localhost" on the command line
might offer some insight.

listen_addresses is not related to this. The stats code tries to bind
to whatever "localhost" resolves as, independently of that.
