PostgreSQL maintainer Simon Riggs has died in a small airplane crash, on Tuesday.
For those who didn't know Simon, he's responsible for PostgreSQL Binary Replication and many big data features. He and I worked together at Greenplum 2006-2008. Postgres would not be the world-leading DB it is today if it weren't for him.

I use Postgres at my home and at work. I thank him and other unknown heroes. He will live forever with Postgres.
