OpenSSL has two ways to store private keys:
1. an own proprietary format
2. standard PKCS#8

The default as used in the postgresql doc is to produce the proprietary format. 
Don't know if PostgreSQL can handle PKCS#8 keys.

If you'd like to check, here is a command to produce PKCS#8:
openssl pkcs8 -in server.key  -out server.p8 -topk8

Jose, writing a tutorial sounds promising. If I can be of any help, just contact me.
