I agree. I will try to narrow it down to a simple example and send it to
IBM.

I agree with that one, too.

Not really. Postgres is runnning at our customers sites, we don't know how
there networks are configured, and we don't know if IP addresses may
change. All we could do is describe the problem as a known bug when using
AIX, IPV6 and postgres together and explain the workaround.
