Re: authentication

Chris,

You can't do what you are trying to do with java. Java does not support
a non-portable concept like unix sockets. So the only way to connect to
postgres from jdbc is through tcpip.

The two jdbc connection URLs you give below are identical in
functionality. If you don't specify the machine and port in the URL it
uses the default values of localhost and 5432.

thanks,
