Beating > the dead horse really does not accomplish anything. I don't think pointing out weaknesses of a proposed solution is equal to beating a dead horse. I see two potential issues here - security and excessive number of connections. Security, because while you can reasonably authenticate the client (e.g. using MD5 authentication), there's no way of encrypting the traffic. But if the data is not sensitive, this might be sufficient. Excessive number of connections, because if you keep one connection from each arduino device, and you have 1000s of devices ... you get the idea. But this might be resolved using pgbouncer + transaction pooling or so. regards Tomas -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
