Re: [BUG?] check_exclusion_or_unique_constraint false negative

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.
