Now run-time errors in arithmetic operators are catched (added PG_TRY/PG_CATCH around operator's functions calls) and converted into Unknown values in predicates as it is required by the standard:
I think we really need to rename PG_TRY and PG_CATCH or rethink this whole interface so that people stop thinking they can use it to prevent errors from being thrown.
I understand that it is unsafe to call arbitrary function inside PG_TRY without rethrowing of caught errors in PG_CATCH, but in jsonpath only the following numeric and datetime functions with known behavior are called inside PG_TRY and only errors of category ERRCODE_DATA_EXCEPTION are caught:
