Notes:

• Communication to Postgres is done exclusively over the private network and the database is not exposed externally in any way by default, if you want to enable access from outside of the private network you can go to the databases settings to enable TCP proxying and enter the internal port (5432) the TCP proxy can be again removed at any point to close off external access. A redeploy is needed after adding the TCP proxy.

Had to modify start script from yarn start to yarn concurrently:start to get this to run.

Thank you for letting me know, I have removed the custom start command from the template since the default is now okay.
