Tunneling Protocols
Tunnel postgres from local machine to server (most common)
ssh -p 22 -L 443:10.x.x.99:443 foo@example.com curl -kL https://127.0.0.1 ssh -L 1111:localhost:5432 user@remote.example.com psql -h localhost -p 1111 -U your-db-username database-name
-g option allows remote hosts to connect to local forwarded ports

Tunneling is nice when using tools like https://www.sqlmanager.net/en/products/postgresql/manager or https://www.dbvis.com/ which are convenient for complex datastores.
Remote Forwarding Tunnel is another option to look at but if you have ssh access/perms to server the above is usually what you will do
