| ### Test 1:
 | |
| ### - While a consistent snapshot transaction is executed,
 | |
| ###   no external inserts should be visible to the transaction.

| start transaction with consistent snapshot;
 | |
| 
 | |

 | |
| connection con1;
 | |
| select * from t1; # if consistent snapshot was set as expected, we
 | |
| # should see nothing.

| ### Test 2:
 | |
| ### - For any non-consistent snapshot transaction, external
 | |
| ###   committed inserts should be visible to the transaction.
