Trying to set a non integer field to primary key results in the field's type to be changed to integer without a warning.
That COULD LEAD TO DATA LOSS!

Reproducible: Always

Steps to Reproduce:
Open a table at design view.
Select a field with a data type other than integer.
Click to make it primary key.


Actual Results:  
The field's type is converted to integer without any warning.
Saving the table could lead to data loss.

Expected Results:  
The user should be prompted that only an integer field is accepted as a primary key, and let the user change the type himself if he wanted.

When a different type could be allowed to be a primary key, the message should be changed accordingly.
