我需要一个触发器来引起reindex(索引在一个不可变的函数上) 我将函数定义为
CREATE FUNCTION "TEST".triggerFuncTest()
RETURNS TRIGGER
AS $$
BEGIN
REINDEX INDEX "TEST"."MyIndex";
RETURN NULL;
END $$ LANGUAGE plpgsql;
带触发器
CREATE CONSTRAINT TRIGGER triggerTest
AFTER INSERT OR UPDATE OF indexes OR DELETE ON "TEST"."MyTable"
DEFERRABLE INITIALLY DEFERRED
FOR EACH STATEMENT
EXECUTE PROCEDURE "TEST".triggerFuncTest();
哪个给出了
ERROR: syntax error at or near "STATEMENT"
但是如果我删除了CONSTRAINT和DEFERRABLE INITIALLY DEFERRED,则会创建触发器,但是这会在触发时引发异常。
