Turn on log_statement.  I don't believe the feature you are asking for
will be nearly as useful as you think.  More than likely, what it
will show you is something like "commit; begin" and you'll be little
wiser than before.  What you'll need to identify the problem will be a
trace of everything the app did; which is what the log is for, not
pg_stat_activity.
