Description:

Messages like this are appearing on logs when receiving new connection:

2014-06-12 10:55:07 UTC [14550]: [1-1] WARNING: pg_getnameinfo_all()
failed: Temporary failure in name resolution
2014-06-12 10:55:07 UTC [14550]: [2-1] LOG: connection received: host=???

Here is resolv.conf:

nameserver 208.67.222.222

Name resolution on host works fine for all basic utilities like ping, dig,
nslookup, wget and so on
