Re: robots.txt sometimes disallowing all?

This behavior seems to still be going on, but I think I have a clue. I
noticed while experimenting with:

wget -O robots.txt http://www.postgresql.org/robots.txt && cat robots.txt

that wget tells me the available servers for www.postgresql.org it has
found in DNS:

Resolving www.postgresql.org... 87.238.57.232, 217.196.149.50, 174.143.35.230

When I fall to 217.196.149.50 and  87.238.57.232, I get the normal
robots.txt. When I fall to 174.143.35.230, I get the bad version
disallowing all access to the site. BTW, this behavior seems to not be
dependent on the user-agent string, contrary to my earlier
speculation. Could someone please check out what's going on with
robots.txt on 174.143.35.230, as it seems to seriously be screwing
with our Google search results.
