How to connect cl+ssl with host ca verification?

[Tim Hawes]

I haven't looked at the code, but apparently, it checks if the rootCA is
registered in the system.
This works if I have added the rootCA system-wide
(let ((cl-postgres:*ssl-certificate-file* "/some/path/to/cert.crt")
       (cl-postgres:*ssl-key-file* "/some/path/to/a-key.key"))
   (postmodern:with-connection
       '("dbname" "dbuser" "password" "some-remote-server.lan" :port 5432
         :use-ssl :full)
     (postmodern:query (:select '* :from 'table))))
