I see that you were wrong about the most used DB in existence and you hand-wave it away because it doesn't fit your narrative.

First of all you don't get to pick which one is a "real" database and which one is not in order to prove your point. The all are.
Secondly the amount of configuration options shown in the links you posted seems to contradict this claim. Even Microsoft's SQL server requires explicit configuration to avoid out-of-memory conditions in certain modes. That's particularly ironic because the documentation goes to great lengths to claim that in regular mode it shouldn't need any kind of setup and will automatically scale memory usage up and down on demand.
Funny thing also: SQL server doesn't detect low memory conditions because you start getting NULL's from malloc() calls, it uses memory resource notifications.
