Hi,

Wouldn't SQL statements in log possible be out of order, also transaction info
would be missing?

Even if you do it in application-side, logging query start time and transaction
info, and feed this data to some application that starts to excecute them in
correct time and context, you wouldnt be able to reliably replicate exact
behavior, cause configuration change might change query times too much.
But i see it _can_ be useful in some cases.
