This is poor configuration, because every certificate listed in root.crt
is considered fully trusted for every purpose.  It's best to keep only
top-level root certs in root.crt.  Instead, put the full chain of
certificates into the client's postgresql.crt, as per the manual:

: In some cases, the client certificate might be signed by an
: "intermediate" certificate authority, rather than one that is directly
: trusted by the server. To use such a certificate, append the certificate
: of the signing authority to the postgresql.crt file, then its parent
: authority's certificate, and so on up to a "root" authority that is
: trusted by the server. The root certificate should be included in every
: case where postgresql.crt contains more than one certificate.

In the JDBC case you'd need to put all those certs into the client's
keystore, which I'm afraid I don't know the details of doing.  Possibly
somebody on pgsql-jdbc could help you with that.
