I think you are misreading the Bityota pages. On the contrary, you CAN run queries with JSON... but you can also just pass in regular SQL statements. I guess Postgres direct protocol is handy; I find that ODBC covers many of my needs, so I haven't actually looked at Bityota as a Postgres drop-in.

Might be worth playing with what Bityota offers; Postgres is awesome but sometimes makes you bend over backwards to do things that are easier in other systems. Paraccel/Redshift has some good extensions, but sometimes there are better ways to do things.
