I need some kind of test:

1. To achieve SELECT from VTI tables before test would start

2. To start a transaction over a table with one column. To initiate insertion N*1000000 records (N - preferable number)

3. While those are processing, I will start ij and achieve SELECT from VTI tables; to how VTI records describe transaction isolation at single moment of time

4. Transaction will finish

5. I will make additional SELECT, to unsure that VTI data is equal to (1) state
