-------------------------------------------------------------
It seems that the PostgreSQL fails on the
{{BulkCreateOrUpdateTest#testConcurrentWithConflict}} without the
{{autoCommit(true)}}.
Update: and sometimes with autoCommit(true) as well.

> It seems that the new bulk createOrUpdate() implementation in RDB is prone
> for the deadlocks. It isn't a bug in the Oak code, but rather something
> related to the database implementations. The bug can be observed if we have
> multiple simultaneous bulk updates and some of the rows repeat among them.
> The attached patch contains an unit test {{testConcurrentWithConflict}}
> presenting the issue.
