Hello, everyone!

Updates so far:
* issue happens with both LOGGED and UNLOGGED relations
* issue happens with DirtySnapshot
* not happens with SnapshotSelf
* not happens with SnapshotAny
* not related to speculative inserted tuples - I have commented the code of
its insertion - and the issue continues to occur.

Best regards,
Mikhail.
