[bersler]

Is your feature request related to a problem? Please describe.
There is a need to include information about session in transaction data.

Describe the solution you'd like
Add fields with values like: user, application name, host.

Describe alternatives you've considered
There is no workaround available.

Additional context
Sometimes certain maintenance transaction should be excluded or processed differently. They could be identified by user, host or application. To allow such operation the transaction data in output should contain information about session parameters.

If there is a demand from users more focus could be given here.
