Comment 8 for bug 391119

Ah, so now it fails with

  2009-07-17 06:27:15 EDT FATAL: could not access private key file "server.key": Permission denied

(This is reported in bug 390748 as well). Assuming that you didn't change it manually, what does

  ls -l /etc/ssl/private/ssl-cert-snakeoil.key

show? It should be

  -rw-r----- 1 root ssl-cert 887 12. Mai 2006 /etc/ssl/private/ssl-cert-snakeoil.key

and "id postgres" should be

  uid=31(postgres) gid=32(postgres) groups=32(postgres),103(ssl-cert)
