Wow, that's surprisingly uninformed for El Reg.

Redshift is based on Paraccel, which is a parallel, column-store DW fork
of Postgres which forked off version 8.2, and has been around since
2007.  Paraccel competes with Vertica Greenplum, Netezza, Aster Data,
and similar DW PostgreSQL forks.

It's DW-only, though; it's completely unsuited to OLTP/webapp workloads.
 Analytics only.
