If your Postgres cluster is not "publicly accessible", you have two options
SSH tunnel: Hightouch will connect to your Postgres cluster via an SSH tunnel established from Hightouch's servers to a bastion server in your VPC.
Reverse SSH tunnel: You will establish an SSH connection from a bastion server in your VPC to Hightouch's servers, and Hightouch will reuse that connection to connect to Postgres.
