Not to everyone. In the referenced section, Hellerstein,
Stonebraker and Hamilton say:
"any good multi-user system has an admission control policy"
In the case of PostgreSQL I understand the counter-argument,
although I'm inclined to think that it's prudent for a product to
limit resource usage to a level at which it can still function well,
even if there's an external solution which can also work, should
people use it correctly. It seems likely that a mature admission
control policy could do a better job of managing some resources than
an external product could.
