Unless I'm mistaken, it's PostgreSQL. The telling feature is the GROUP BY clause - PostgreSQL allows you to group by column index.
http://www.postgresql.org/docs/9.0/static/sql-select.html#SQL-GROUPBY Since this is an eccentricity of PostgreSQL, it would be a good idea for us to modify that example in the docs, and use a more conventional GROUP BY statement that would be familiar to all SQL dialects. I've opened ticket #20168 to track this issue.
