Hello,
The goal is not to find slow queries in a transaction, but troubleshoot
applicative issue when you have short queries.
Sometimes you want to understand what happens in a transaction, either
you perfectly know your application, either you have to log all queries
and find ones with the same transaction ID (%x). It could be problematic
if you have a huge traffic with fast queries.
Thanks,
