It is worth pointing out that AsterData and Redshift are built on pgSQL. From what I have read, this is due to licensing issues. MySQL is ok but I'm unconvinced that MySQL is a good option for single instance terabyte size databases. I'm not sure if pgSQL is any better but you hardly see large unwieldy pgSQL instances. Large slow MySQL instances are everywhere. And it's frustrating.
