A design I have seen in some other systems is that you specify as a configuration parameter an address by which you want to be contacted by admin tools. This might be overkill here since we only need to be contacted by a local client and the discussion is hoping to handle those cases, but if not it would be a more principled solution. -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
