Changes:
* attempt to remove object restrictions and allow operations on arrays and scalars.
* add a single text only key delete function
* unsure how operations on jsonb arrays should work, if for example arrays elements are numeric or boolean
possible angles are:
do some funny casting to text :-(
create separate functions taking (jsonb, int), (jsonb, bool) etc :-(
