Ok, I might be seeing whats going on here. Could you go to 'printtup'
and print *myState, *myState->attrinfo, *typpeinfo?
Tom: It looks to me like printtup_prepare_info won't normally be called
in an held cursor. But if some concurrent DDL changed the number of
columns in typeinfo vs thaose in the the receiver that could explain the
issue and why its not seen all the time, right?
