1. I assumed that in this patch modification in case of OIDs= True (without primary key) has not considered as that is not working.
This is not implemented yet. I will work on that in a following patch soon enough.
2. As we are already showing the changed Data prompt on closing the Query Tool, do we really need the Uncommitted Transaction prompt?
This is needed when auto-commit is off. Saving changes in the data grid is performed as part of the ongoing transaction (or a new one if none is ongoing). After saving the data changes the user should still commit the current transaction for the changes to be commited to the database. This feature is also useful in general when auto-commit is off as users may forget to commit ongoing transactions.
