Instead, it now returns a value indicating either success or the type of error which occurred. The old behavior is still available by calling pg_parse_json_or_ereport(). If the new interface is used, an error can be thrown by passing the return value of pg_parse_json() to json_ereport_error(). pg_parse_json() can still elog() in can't-happen cases, but it seems like that issue is best handled separately. Adjust json_lex() and json_count_array_elements() to return an error code, too. This is all in preparation for making the backend's json parser available to frontend code. Reviewed and/or tested by Mark Dilger and Andrew Dunstan. Discussion: http://postgr.es/m/CA+TgmoYfOXhd27MUDGioVh6QtpD0C1K-f6ObSA10AWiHBAL5bA@mail.gmail.com
