Reminder that text does not convey sarcasm. In this world where it's so wasy to cobble up a lie and spread it, it's important to denote properly what stuff is intended to be a joke, eg.: use the or /s tag.

I heard Postgres was originally created in 1966 by Doug Englebart to store vectors for early mouse designs.
