Is there any reason why /etc/hosts would be missing the line,
127.0.0.1 localhost?
I just spent an hour trying to figure out why I could not connect
to postgresql using ``psql -h ...', finally figuring out that
the /etc/hosts file was the problem.

To say that UNIX is doomed is pretty rabid, OS/2 will certainly play a role,
but you don't build a hundred million instructions per second multiprocessor

Nope. It's there by default in some form or another.
If you don't have anything like this in your /etc/hosts, you either
need to find a mirror and begin yelling at responsible parties, or
stalk whomever else has root on this particular machine.

I guess I could yell at myself as I'm doing kickstart installs from
a local mirror.
I found the same thing on two CentOS 5.1 installs here, one on a
VMware VM, the other on real iron. The wierd thing is that the
base VMware VM I have that I copy to create new VMs looks OK.
Now I'm going to have to poke around to see what's causing this
line to be deleted.

I had a similar problem using OpenVZ images, installed from kickstart -
almost like it's leaving some stuff out by default. So I ended up
creating the file manually and adding it to the kickstart file to be
copied over.

The file was OK after the kickstart install, and after a ``yum update'.
We install about 240 packages under the OpenPKG portable package management
system which may have caused this, but I have not seen this problem prior
to CentOS 5.2.
I did not check to see the status of the /etc/hosts file after configuring
the network with system-config-network, and before installing OpenPKG and
its packages. I may create a new VM, and run through the network
configuration etc. to see where this is happening (VMware snapshots and
revert sure simplify things like this :-).

I just did a fresh kickstart install of CentOS 5.2 as a VMware
virtual machine, and the 127.0.0.1 localhost line is missing
after doing ``yum update' when I run ``system-config-network'
to assign a static IP address to the new VM.

The cry has been that when war is declared, all opposition should
therefore be hushed. A sentiment more unworthy of a free country could
hardly be propagated. If the doctrine be admitted, rulers have only to
declare war and they are screened at once from scrutiny ... In war,
then, as in peace, assert the freedom of speech and of the press.

There were no problems with the postgresql settings, only that
when trying to connect to ``localhost' it could not resolve that
to 127.0.0.1. ``psql -h 127.0.0.1 ...' worked. After updating
the /etc/hosts file to create the ``127.0.0.1 localhost' line,
things work fine.
