Обсуждение: postmaster udp ports?

Does anyone know what postmaster is doing with these UDP ports?
On a fresh installation these ports are opened  and I cannot find any
documentation on what they are for....

postmaste 5398 postgres    3u  IPv4  53988       TCP *:5432 (LISTEN)
postmaste 5398 postgres    5u  IPv4  53994       UDP ucs:32774->ucs:32774
postmaste 5400 postgres    5u  IPv4  53994       UDP ucs:32774->ucs:32774



Thanks
Andrew
