BTW, I've some general idea about jsonpath documentation structure.
Right now definition of jsonpath language is spread between sections
"JSON Types" [1] and "JSON Functions, Operators, and Expressions" [2].
Thank might be confusing.  I think it would be more readable if whole
jsonpath language definition would be given in a single place.  I
propose to move whole definition of jsonpath to section [1] leaving
section [2] just with SQL-level functions.  Any thoughts?
