使用新列在父级 table 上插入失败

Question

我有一个主要的 table（付款）和一些分区的 tables (payment_AAAA_MM)。我获得了这些 tables 与这样的存储功能：

CREATE OR REPLACE FUNCTION partitioning_payment()
  RETURNS trigger AS
$BODY$
 DECLARE
 numero integer;
 month float;
 year float;
 monthp float;
 yearp float;
 months text;
 monthps text;
 
 BEGIN
 month=DATE_PART('month',NEW.REQUEST_TS);
 year=DATE_PART('year',NEW.REQUEST_TS);
 monthp=month;
 yearp=year;
 months=month;
 monthps=monthp;
 IF month = 12 THEN
 yearp=yearp+1;
 monthp=1;
 ELSE
 monthp=monthp+1;
 END IF;
 monthps=monthp;
 IF(length(month::text)=1) THEN
 months=month::text;
 months='0' || months;
 END IF;
 IF(length(monthp::text)=1) THEN
 monthps=monthp::text;
 monthps='0' || monthps;
 END IF;
 EXECUTE 'SELECT count(*) FROM PG_TABLES WHERE SCHEMANAME=''public'' AND TABLENAME=''payment_' || year || '_' || months || '''' INTO numero;
 IF numero=0 THEN
 EXECUTE 'CREATE TABLE payment_' || year || '_' || months || '(CHECK ( REQUEST_TS >= ''' || year || '-' || months || '-01 00:00:00'' and REQUEST_TS <  ''' || yearp || '-' || monthps || '-01 00:00:00'' )) inherits (payment)';
 END IF;
 
 EXECUTE 'INSERT INTO payment_' || year || '_' || months || ' (id,id_request,REQUEST_TS,response)
 VALUES (
 '''||NEW.ID||''',
 '''||NEW.ID_REQUEST||''',
 '''||NEW.REQUEST_TS||''',
 '''||NEW.RESPONSE||'''
 )';
 RETURN null; END;
$BODY$
  LANGUAGE plpgsql VOLATILE
  COST 100;

CREATE TRIGGER partitioning_payment
  BEFORE INSERT
  ON payment
  FOR EACH ROW
  EXECUTE PROCEDURE partitioning_payment();

一切正常。

现在，我必须向父级 table 添加一列（is_test 整数类型）。我在parent table中添加了column，并以这种方式修改函数

CREATE OR REPLACE FUNCTION partitioning_payment()
  RETURNS trigger AS
$BODY$
 DECLARE
 numero integer;
 month float;
 year float;
 monthp float;
 yearp float;
 months text;
 monthps text;
 
 BEGIN
 month=DATE_PART('month',NEW.REQUEST_TS);
 year=DATE_PART('year',NEW.REQUEST_TS);
 monthp=month;
 yearp=year;
 months=month;
 monthps=monthp;
 IF month = 12 THEN
 yearp=yearp+1;
 monthp=1;
 ELSE
 monthp=monthp+1;
 END IF;
 monthps=monthp;
 IF(length(month::text)=1) THEN
 months=month::text;
 months='0' || months;
 END IF;
 IF(length(monthp::text)=1) THEN
 monthps=monthp::text;
 monthps='0' || monthps;
 END IF;
 EXECUTE 'SELECT count(*) FROM PG_TABLES WHERE SCHEMANAME=''public'' AND TABLENAME=''payment_' || year || '_' || months || '''' INTO numero;
 IF numero=0 THEN
 EXECUTE 'CREATE TABLE payment_' || year || '_' || months || '(CHECK ( REQUEST_TS >= ''' || year || '-' || months || '-01 00:00:00'' and REQUEST_TS <  ''' || yearp || '-' || monthps || '-01 00:00:00'' )) inherits (payment)';
 END IF;
 
 EXECUTE 'INSERT INTO payment_' || year || '_' || months || ' (id,id_request,REQUEST_TS,response,is_test)
 VALUES (
 '''||NEW.ID||''',
 '''||NEW.ID_REQUEST||''',
 '''||NEW.REQUEST_TS||''',
 '''||NEW.RESPONSE||''',
 '||NEW.IS_TEST||'
 )';
 RETURN null; END;
$BODY$
  LANGUAGE plpgsql VOLATILE
  COST 100;

但是，现在我遇到了这样的情况：

在父 table 和分区 table is_test 存在
如果我在分区 table 上插入，我有新行
如果我在父 table 上进行插入，什么也不会发生

那么，我怎样才能正确添加新列并允许我在父列上插入 table？

好吧……真丢人。我已经更新了程序，但您必须删除并重新创建付款触发器 table
