You need to change permissions to get your postmaster working.

"To start in SSL mode, the files server.crt and server.key must exist
in the server's data directory. These files should contain the server
certificate and private key, respectively. On Unix systems, the
permissions on server.key must disallow any access to world or group;
achieve this by the command chmod 0600 server.key. If the private key
is protected with a passphrase, the server will prompt for the
passphrase and will not start until it has been entered."
