+
+        
+         Previously, the sequence restart did not roll back on error.
+         This meant that an error between truncating and committing
+         left the sequences out of sync with the table contents, with
+         potentially bad consequences as were noted in a Warning on
+         the TRUNCATE man page.

+        
+        
+         This was found to be confusing in some cases.  The
