[DEV] Connect to PostgreSQL database on Docker host system



I set up a local install with Docker following these instructions: https://redash.io/help-onpremise/dev/docker.html

I am now having a hard time figuring out how to connect to a PostgreSQL database on the host system (my local machine).

Should this be possible? If so, how?

This may be a similar/identical concern as described in this issue: Connect to PostgreSQL after vanilla install

I have already updated my Postgres config (pg_hba.conf, postgresql.conf) according to the second link provided by @dncpax in the above post.
