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))))

Postmodern uses cl+ssl and I do not see cl+ssl using a root ca. Maybe I am missing something in that library?

That works, but it looks like the root ca has to be added to the system. If using psql I could specify where all the certs I want to use to connect with like so:
$>psql "port=5432 host=localhost user=postgres sslcert=./test/client.crt sslkey=./test/client.key sslrootcert=./test/server.crt sslmode=verify-full" Is there an equivalent in Postmodern?

The cl-postgres (open-database ...) function has :use-ssl as a key parameter where the parameter values:
- :try means if the server supports it
- :require means use provided ssl certificate with no verification
- :yes means verify that the server cert is issued by a trusted CA,
but does not verify the server hostname
- :full means expect a CA-signed cert for the supplied hostname and
verify the server hostname
This is mirrored in the postmodern (connect ...) function.
If I understand your question correctly, you want to use :full as the parameter passed to :use-ssl. E.g.
(connect "test_db" "test-user" "test-password" "192.168.5.223" :port 5434 :pooled-p t :use-ssl :full)
But maybe I am not understanding your question correctly.

I am not finding any helpful information in how to connect to PostgreSQL using client key/client cert and a root ca for verifying the host with Postmodern. Can someone send me an example?
