I would love it if even one of the database experts who are so sure that the comparisons are somehow rigged, would actually run their own benchmark to prove it wrong instead of just speculating.

Get any moderately sized table (millions of rows and a dozen or more columns) on your 'highly-tuned' postgres database with all the proper indexes in place and load that same data into Didgets (takes a whole 10 minutes to download the software and start using it) and run whatever queries suits your fancy.
