Thank you for your valuable inputs. 

Agreed, with the help of two workarounds we can pull the trx-timestamp one with additional-column/trigger and another with log_line_prefix from pg_log/logs. 

However, I was curious to know any thing stored at Page-Level(like XID) to help me in getting the transaction timestamp.

Short answer: You can't. Instead, add a new "timestamptz default
now()" column, that will get you the time of the insert.

If you want the update time, create a BEFORE UPDATE ON x FOR EACH ROW
trigger on this table to update it.

Marti
