In reference to this thread, from several months ago:
http://archives.postgresql.org/pgadmin-support/2005-12/msg00021.php
I don't know if this was ever solved elsewhere on the list, but it took
me some time to figure out what I think is the cause of the symptom.
I believe whenever I specify the address of a registered server as an IP
address, it doesn't work. If I use a domain name instead, it does work.
Do the developers agree? Was this already discovered earlier? If not,
could it be addressed in future releases?
Thanks,
jl
