运算符不存在：Postgresql中的json - text []错误

Question

我尝试使用此查询删除Postgresql表中的某些行：

DELETE FROM log_sp_montreal_test.person_contact 
WHERE id NOT IN (SELECT id FROM log_sp_montreal_test.person_contact limit 100)

我正在使用PgAdminIII，但是当我在SQL编辑器中运行它时，我得到了这个奇怪的错误：

    ERROR:  operator does not exist: json - text[]
LINE 1: SELECT row_to_json(OLD.*)::json - ignored::TEXT[]
                                        ^
HINT:  No operator matches the given name and argument type(s). You might need to add explicit type casts.
QUERY:  SELECT row_to_json(OLD.*)::json - ignored::TEXT[]
CONTEXT:  PL/pgSQL function log_sp_montreal_test.add_journalization_entry() line 17 at assignment
********** Error **********

id是一个uuid，但是这个错误是什么？如何运行它？
