Dear all,
Imagine I have two users "Maria" and "Ana" using a PHP site.
There is a common Postgres user "phpuser" for both.
I'm creating audit tables to track the actions made by each PHP site user.
I have used the following code:CREATE OR REPLACE FUNCTION MinUser_audit() RETURNS TRIGGER AS $usr_audit$
BEGIN
IF (TG_OP = 'DELETE') THEN
INSERT INTO MinUser_audit VALUES (DEFAULT, 'D', now(), user, OLD.*);
RETURN OLD;
ELSIF (TG_OP = 'UPDATE') THEN
INSERT INTO MinUser_audit VALUES (DEFAULT, 'U', now(), user, NEW.*);
RETURN NEW;
ELSIF (TG_OP = 'INSERT') THEN
INSERT INTO MinUser_audit VALUES (DEFAULT, 'I', now(), user, NEW.*);
RETURN NEW;
END IF;
RETURN NULL;
END;
$usr_audit$ LANGUAGE plpgsql;
Everything seems to wok fine except the
user information I'm getting, in this case "
phpuser".
I would like to have not the postgres user but the PHP site user (
Maria or Ana).
How can I pass the PHP site user (Maria or Ana) into Postgres in a clever way?
I have done several web searches and found nothing for Postgres. I found a solution for oracle:
http://www.oracle.com/technetwork/articles/dsl/php-web-auditing-171451.html
They use a "client identifier" feature. Is there a similar way to do this in Postgres?
Thanks in advance.
