如何知道对postgres SQL表执行的所有操作？

Question

I am looking for a way to know all the events occurred on a specific table without enabling postgres logs.

Just want to know weather the sequence of addition/deletion/ Modification.

Thanks

对于postgres中的审计跟踪，您必须编写一个函数并在触发器中调用它，请查看wiki.postgresql.org/wiki/Audit_trigger ，您将必须编写一个函数，说明是否进行更新，删除或插入。如果发生在表上，它将触发一个操作，该操作将更新审核表，以捕获所需的信息，例如ip地址，查询，旧数据，新数据，发生的操作的时间戳等。

You can create triggers (see postgres docs ) to observe all changes, eg:

CREATE TRIGGER insert_trigger AFTER INSERT ON my_table
EXECUTE PROCEDURE insert_function();
CREATE TRIGGER update_trigger AFTER UPDATE ON my_table
EXECUTE PROCEDURE update_function();
CREATE TRIGGER delete_trigger AFTER DELETE ON my_table
EXECUTE PROCEDURE delete_function();

or do this with just one function:

CREATE TRIGGER universal_trigger AFTER INSERT OR UPDATE OR DELETE ON my_table
EXECUTE PROCEDURE universal_function();
