Beyond a few terabytes of data, Postgres is just as worthless as MySQL, and every other non-experimental SQL option comes with a "call us" price tag.

If there are production-ready options for biggish data other than NoSQL or high priced commercial analytics dbs, please share...

Considering the space requirements of a DB with a properly designed schema, I have to wonder what on earth you can do that generates beyond a few terabytes of data, and how you can make any sense out of it.

Also, your comment is rather ambiguous, I certainly hope you're not calling Postgresql experimental, because that would be laughable; and there are several examples of multi-terabyte databases using it.
