pgAdmin has to look up the address of the server you're trying to
connect to. It's not in the docs or any FAQs because it's such a basic
operation that almost every TCP/IP network program on the planet will
also do.

Functions like gethostbyname() are written by Microsoft, not us. If they
don't return, there's not much we can do. I suppose we could run every
system call in a different thread so we can abort if it doesn't return,
but that would bring a whole new meaning to the term 'bloatware' and
would probably mean we would still be writing the connect code.

Configure a sensible firewall policy that allows pgAdmin to perform
lookups? If your firewall doesn't allow you to do this, throw it in the
bin and get a decent one.
