    It's been about a decade since I looked at cse vs autoincrements, so
    the details have faded from memory.  [The original context I found the
    problem was in an attempt to run cse after reload. ]

My recollection is that we never used to allow autoincrements before CSE
with the exception of autoinc on SP.
