Just to be clear: right now, if "localhost" doesn't resolve then the
stats collector will not start, but this doesn't prevent use of the
database.  It might be a good idea to ensure that the same is still true
after making this change; that is, invalid entries in listen_addresses
should only provoke warnings and not refusal to start (assuming that
we are able to find at least one valid socket to listen to, of course).
I believe that right now, any bad entry in virtual_host causes the
postmaster to error out.  That's defensible from one point of view but
on balance I think it's overly paranoid.  Any other opinions out there?
