some requests on auditing

Hi

I am working on pgaudit customization for one my customer.

There are few requests:

1. flat format without complex types, without nesting - CSV is ideal.
2. all important attributes should be separated - is not possible to search
in original queries: table name, database name, role name, rights.
3. if it is possible - own log file
4. one statement can have more rows (flat format is required), but it
should be logged only once success/failed
5. any activity should be logged

The point @4 is hard to implement - static audit should be linked with
result together. There is not any top level hook.

Regards

Pavel
