Support client authentication for postgres

Thanks for replying so quickly. My use case really revolves around the way our database is secured. Typically a client will request access and certificates are issued through a Vault. So in my case I only have 3 certs and no password is issued.

Hi @frostpuppet, sorry for the late response. We have added the support for client authentication in our newest version 0.2.5. To set up the certs and keys, you need to add the url params like this "?sslmode=require&sslrootcert={postgres_rootcert}&sslcert={postgres_sslcert}&sslkey={postgres_sslkey}". Can you try to see whether it works?
