People are always complaining about hosting companies not supporting
Postgres but put yourself in the shoes of a hosting copmany that wants
to have a few hundred hosting clients all on the same box, either as a
shared box or more likely these days as VMs. That's perfectly
reasonable if they're all idle nearly all the time but if they're all
waking up ever few milliseconds that's going to consume a substantial
amount of cpu before you even start handling requests.
