I'm running postgresql on ubuntu. the 9.4 branch from postgresql.org I think the only way to disable ipv6 is to edit postgresql.conf and explicitly state localhost in ipv4 as follows - listen_addresses = 'localhost' + listen_addresses = '127.0.0.1' can anyone confirm? -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
