Permissions are OK. I have working:


    -rw-r--r--  1 postgres postgres  615 2011-04-25 16:23 root.crt
    -rw-------  1 postgres postgres  692 2011-04-25 17:20 server.crt
    -rw-------  1 postgres postgres  887 2011-04-25 17:17 server.key

Try to put this files in data directory
(/var/lib/postgres/9.0/{clustername}), not config directory
(/etc/postgres/9.0/{clustername}).

When cluster is created there is automatically provided snakeoil
server.key and server.crt in data directory, but there is not root.crt
provided. Propably you put your certs in config directory.
