Comment (by André Ericson):
Hey,
how should we tackle this? psycopg2 documentation says "in order to
include a literal % in the query you can use the %% string."
If we decide to escape it, it will break for people that already fixed
this in their own code by pre-escaping the JSON keys (ie: '%%total' key).
Another approach would be to add a note in the JSONField documentation
that '%' must be escaped.
