Install Postgresql

Postgresql is amongst the safest Open Source databases. Rock solid and simple to maintain - year after year. In my case it is used both as a "lookup" database (static contents) and as a "real" database (CRUD contents). The lookup database should be on localhost, but the CRUD database can be on another VPS. Note that Upcloud can connect to this "external" database by a local IP address. Every VPS on Upcloud has 2 IP-addresses. The internal IP-address can be reached only from another VPS not reachable from the outside internet.

Refresh Moduls to reach the Webmin Postgresql Manager

To administer Postgresql I recommend pgAdmin installed on your local computer. It is way better than Webmin Postgresql Manager. Note that you must edit /etc/postgresql/11/main/postgresql.conf :

listen_addresses = '*' # what IP address(es) to listen on;
