Hi,
I created a PR to run test on travis against pg8000 too, 
https://github.com/web2py/web2py/pull/530. Given that we can check what 
works and what doesn't.
I'd suggest that you can open an issue 
here https://github.com/mfenniak/pg8000/issues regarding the missing 
feature of having json as field type.
