Tunneling

• 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.
