What exactly prevents the client role from inserting e.g.

- 'robert''); drop table students; --'
- millions of 'cat' rows
- millions of 1GB-large rows

or just keep sending massive invalid query texts to fill the logs, or just
trying to connect until there's no available connection slots anymore, and then
keep spamming the server thousands of time per second to try to open new
connections, or ...?
