Your machine is connecting to PostgreSQL using IPv6's "localhost" address. IPv6 is a newer format of IP addressing that allows for more IP addresses - ::1 = 127.0.0.1, basically.

Newer TCP/IP stacks attempt to connect to localhost using the IPv6 address first, instead of IPv4 (the current format.)

When you connect, try passing "-h 127.0.0.1" to psql or whatever app/library you're using. That should force it to connect over IPv4. Or just uncomment the IPv6 line in your pg_hba.conf and restart PostgreSQL.

Is the different application on a different server? If so, it could be that the other app's OS is using IPv4 by default instead of IPv6. Or the app is connecting over an IPv4 address (e.g. 127.0.0.1) instead of "localhost."
