PostgreSQL 8.4 documentation update

[Nicolas]

in the install guide it is mentioned to put this line into
postgresql.conf:

tcpip_socket = true

But when I restart the sql-server, it gives me following error:

FATAL: unrecognized configuration parameter "tcpip_socket"

In another forum I read, that since version 8. of postgresql the
command listen_addresses is used instead and points to localhost per
default.

fixed in v8.4.
