Dear all,

I am a newbie to postgresql. After installing Postgresql 8.0.3, I run postmaster and get an error (log). Please help me ! Thanks in advance.

Hi,

i also get this error message but only at one of my database servers.
I'm not sure, but I have experienced some other IPv6 issues on the same
server. I think somebody turned on the IPv6 protocole on the server and
didn't declare in postgres the IPv6 address. Check if this is also true
in your case.

Regards,

Aldor

Actually, what this suggests is that your kernel doesn't support IPv6
but userland libraries (getaddrinfo() in particular) think it does.
It's pretty harmless and you could just ignore it, unless of course
you actually need to use IPv6 ...
