The certDb (proton: pn_ssl_domain_t::pn_ssl_domain_trusted_certificate_db) is the database/collection/store of CA certificates which are used to validate the authenticity of the peer's certificate (client or server). For self signed certificates, at least the public portion of the certificate itself must be in the database (since it is its own CA).
The trustedCerts (proton pn_ssl_domain_t::pn_ssl_domain_set_peer_authentication) is a server-only attribute specifying the list of CA's that will be included in the "client certificate request" portion of the first SSL handshake packet from the server to the client. In theory, Proton could allow the application examine this list and provide its preferred client certificate for that server, but it currently requires a single certificate to be specified before socket creation, and it does not change during SSL negotiation. Proton could also allow the server to change the list based on the client's IP address or other client hello context, but again the value is fixed before listener socket creation. I am not sure if there is a good use case to specify the two with different values for messaging applications requiring client certificates, but the ability is there for the static case. They are separately (and dynamically between handshake stages) configurable in both OpenSSL and SChannel, so it is clear some SSL applications need the flexibility.
