Here's the documentation on how to specify the parameters of the
connection.  This is from the libpq documentation:

http://www.postgresql.org/docs/7.3/static/libpq-connect.html

> host
>
>    Name of host to connect to. If this begins with a slash, it specifies
Unix-domain communication rather than TCP/IP communication; the value
is the name of the directory in which the socket file is stored. The
default is to connect to a Unix-domain socket in /tmp.
>
> hostaddr
>
>    IP address of host to connect to. This should be in standard
numbers-and-dots form, as used by the BSD functions inet_aton et al.
If a nonzero-length string is specified, TCP/IP communication is
used.

Therefore, using a hostname like xyz.org (is that a preconfigured "please
edit me" default?) with hostaddr is clearly wrong--the option is meant for
numeric IP addresses only, for the specific case that you don't wish to
allow hostname lookups.  Using "host" instead of "hostaddr" (or simply
setting the PGHOST environment variable instead) is going to fix at least
that side of the problem.
