FYI / For the record
session.query(User).\
filter(User.prefs.has_key('inboundBusStop')).\
update({User.prefs: User.prefs.delete('inboundBusStop') },
synchronize_session="fetch")
The above deletes a key in an efficient manner.
UPDATE user_data SET prefs=delete(user_data.prefs, %(param_1)s)
WHERE user_data.prefs ? %(prefs_1)s
{'prefs_1': 'inboundBusStop', 'param_1': 'inboundBusStop'}
