Re: How to get Transaction Timestamp ?

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.
