How to get Transaction Timestamp ?

Respected All,

Can we get the transaction timestamp for INSERT/UPDATE/DELETE ran against
table in the database ?

postgres=# create table trx_test(id int, name char(30));
CREATE TABLE
postgres=# insert into trx_test VALUES (1,'AAA');
INSERT 0 1
postgres=# insert into trx_test VALUES (2,'BBB');
INSERT 0 1
postgres=# insert into trx_test VALUES (3,'CCC');
INSERT 0 1
postgres=# select xmin,* from trx_test ;
xmin | id | name
---------+----+--------------------------------
1348711 | 1 | AAA
1348712 | 2 | BBB
1348713 | 3 | CCC
(3 rows)

We can get a Transaction ID, but not the transaction timestamp when it
performed.
Kindly advice me.
