I fully support this addition to the documentation. The legal
possibility of breaking data consistency must be documented at least.
Please, consider small suggestion to replace last sentence.
- This is not considered a bug, and it is the responsibility of the user
to write triggers so that such problems are avoided.
+ It is the trigger programmer's responsibility to avoid such scenarios.
To be consistent with the sentence about recursive trigger calls: [1]
"It is the trigger programmer's responsibility to avoid infinite
recursion in such scenarios."
Also I don't really like "This is not considered a bug" part, since it
looks like an excuse.
