Hi Niphlod,
I deleted all the scheduler tables , created a new database and then 
rebooted with DAL(..migrate=True..) yet still get this error
column "worker_stats__tmp" is of type json but expression is of type text'

using postgresql 9.4 on raspberry pi.
In 
http://stackoverflow.com/questions/32501027/casting-text-type-column-to-json-type-in-postgresql
there is a mention of recasting. If this is a solution, would you know how 
I can incorporate this into web2py?
thanks,
Ben
