Per here:
http://www.postgresql.org/docs/8.4/static/ssl-tcp.html
File Contents Effect
server.crt server certificate requested by client
server.key server private key proves server certificate sent by owner;
does not indicate certificate owner is trustworthy
root.crt trusted certificate authorities checks that client certificate
is signed by a trusted certificate authority
root.crl certificates revoked by certificate authorities client
certificate must not be on this list
