How to configure conjur DATABASE_URL with postgres ssl_mode=verify-full

Question

I would like to configure Conjur with ssl_mode=verify-full to connect to my postgres database.

I use the Docker image cyberark/conjur:1.8.1@sha256:01d601d763edf1d98ca81dda36d4744e78244a4836cfa804570a47da5fd50405

Adding it as a string parameter (like that DATABASE_URL=postgres://conjur:$CONJURDBPASSWORD@postgres-conjur:5432/conjurdb?sslmode=verify-full) does not seem to work.

The db library used by Conjur is Sequel and it supports it https://sequel.jeremyevans.net/rdoc/files/doc/opening_databases_rdoc.html#label-postgres

How can I achieve that without altering the Conjur code ? Ideally, via ENV or mounting a config file.

A project like Gemstash uses the same library and gives a way to achieve that easily. with a config.yml file containing (for instance):

:db_adapter: postgres
:db_url: postgres://{{ .Env.DB_HOST }}/gemstashdb?user=gemstash&password={{ .Env.DB_PASSWD }}
:db_connection_options:
  :connect_timeout: 10
  :read_timeout: 5
  :timeout: 30
  :sslmode: 'verify-full'
  :sslrootcert: '{{ .Env.HOME }}/.ssl/root.crt'

I didn't find anything similar in Conjur.
