I have two stores, physically separated, in one of them I have a local network with several computers running odoo on one computer as a server, I want to access odoo from the second store through ngrok, pagekite or localxpose. I am in doubt as to whether it is better to expose the odoo server port or, expose the postgresql port and run odoo locally and connect it to the remote database, would there be any problem if I do the latter, what happens if I install an application on one of them?
