Hi, John! > I think the pg_hba.conf is OK.. > # "local" is for Unix domain socket connections only > local all all ident sameuser > # IPv4 local connections: > host all all ***.*.*.*/** ident sameuser > # IPv6 local connections: > host all all ::*/*** ident sameuser Note that the above configuration will use 'ident sameuser' authentication for connections via tcp/ip (like the one you're trying from your webserver). So, your connection will need an OS account (and no password supplied). That's what your error_log is telling you, and I'm guessing that the account you're supplying for the connection is not an OS account, but a Postgres account. If you want to use Postgres account authentication (e.g. users created via CREATE USER in Postgres DB), perhaps you should try md5 authentication in your pg_hba.conf.
