It looks like the immediate problem can be resolved by just adding
a check for conn->pghost not being NULL, since the comment above
says
* Per RFC 6066, do not set it if the host is a literal IP address (IPv4
* or IPv6).
and having only hostaddr certainly fits that case. But I didn't
check to see if any more problems arise later.
