Dear All,

I’ve got a need to change sort order for jsonb field. I’m looking for a way to change “order by” behavior like it is described in my previous question.

I’ve found a piece of doc which says that it is possible to override method “int compare(Datum a, Datum b)” here:
https://www.postgresql.org/docs/9.5/static/gin-extensibility.html

I wonder if there are any examples available? 

If not I’m opened to offer my help in making one.
