You seem to be rather seriously confused --- that is certainly not a 7.3
postmaster, because there was no IPv6 support in PG 7.3; nor was there a
writer subprocess before 8.0, so I'm betting this is actually 8.0.something.
It would appear that you've got two different generations of Postgres
installed on that machine, and they are fighting over which one owns the
database directory. In fact, you may have pieces of *three* versions,
because it says here that RHL 7.3 shipped with Postgres 7.2.something.
This is a recipe for shooting yourself in the foot :-(. I'd suggest
figuring out which version you actually wish to be running, and removing
all traces of the other version(s), and then making sure that the system
boot process correctly starts the version you want to run.

8.0 defaults to accepting only local TCP connections; if you want it to
accept remote connections, set listen_addresses to '*' in
postgresql.conf (and restart the postmaster). Pre-8.0, set tcpip_socket
to true, instead.
