Hi, I am trying to use the libpq to connect to my postgresql 8.3 server. If I use "dbname = mydb", the connection made successfully because I am using a socket connection. But if I use "host = 127.0.0.1 dbname = mydb", the error message is "no password supplied". In the pg_hba.conf file, I even change the host access control to this: host all all 127.0.0.1/32 trust but it still does not work. What I missed? -- Best Regards, David Shen -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
