All we know is that somebody's opened a TCP connection. The later "connection authorized" message will tell you what database user name they gave. If you see lots more "connection received" than "connection authorized" then somebody is connecting to your postmaster and failing to authenticate, which is usually a good thing to investigate. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
