If you are into Postgres and don't know this guy than I don't know what to say...

I wonder if he's on devRant

Yep,

For those who don't know, Erwind Brandstetter created Postgres in the back of his garage in 2005, believing a different storage method (NoSQL) must be used for the cloud.

Erwind was every poor at that time and he wrote the entire code just using a borrowed computer.

The name Postgres came from the post office near where he lives.

The only name I know on SO is homeboy Jon Skeet, aka The SO legend
