Multiple txns are inserting tuples into a table concurrently. Wanted to
measure
the total time taken to complete the insertion process. Some txns
overlap with
others on the tuples they insert. Duplicate tuples are not inserted.
The duplicate elimination is being handled by ON CONFLICT or some custom
process in the code generating the transactions?
If the transactions are being created from a single app/script could you
not just use 'timing' to mark the beginning of the transactions and the
end and record that somewhere(db table and/or file)?

Well different sessions be they psql or some other client. That
would be
the difficulty, determining what is submitting the transaction.

It would help to know what problem you are trying to solve?
