It is a massively-parallelization of what is supposedly originally PostgreSQL 8.0.2 - but apparently with some differences even in SQL coverage between the two. The parallelization uses Actian's ParAccel infrastructure (and note that Actian also offers the Vector DBMS).
Amazon already had a parallelized relational DBMS service before RedShift, RDS - but that one is not column-based.
