the abbrev_converter is applied whenever it is defined. The values are sorted using the abbreviated comparator first using the shortened version, and if there is a tie the system asks the real full comparator to resolve it.
I am trying to implement a sort support function for geometry data types in PostGIS with the new feature `SortSupport`. However, I have a question about this.
I think it is hardly to apply a sort support function to a complex data type without the `abbrev_converter` to simply the data structure into a single `Datum`. However, I do not know how the system determines when to apply the converter.
I appreciate any answers or suggestions. I am looking forward to hearing from you.
