What exactly do you have for the URL in the first argument to
getConnection?  If you have a direct IPv6 address like
jdbc:postgresql://::1 it will not work at the moment because it tries to
parse the url using the colon as a delimiter which works fine for IPv4
addresses, but not IPv6 see org.postgresql.Driver#parseURL for more info.

What happens if you are using a name that resolves to an IPv6 address?
You're probably the first person to actually try this.  I will look into
this further, but it may take me a while to get IPv6 up and running on my
machine.
