All CREATE SERVER clauses are optional. Default values are:
- HOST: ''
- PORT: 0
- SOCKET: ''
To have a usable server, we must define:
(host AND port) OR socket
No storage engine returns a clear error when trying to connect to an unusable server. And with SPIDER, bad things happen.
Could MariaDB return an error/warning/note, when not enough data or too many data are provided?
