no verification of client certificate?

8.2.3

I was hoping to not have to support client certs.  I want
encryption and to verify the server, but no to verify the client.
Does this work and I've got the config wrong?

I get ssl connections if I add in the .postgresql/postgresql.crt+key.
Results seem similar to this report:
