Well, the objects indices 1,2,3 point to changed when you changed column a4, but I don't know if that's the reason. I would guess that the indices are structured as pointers of some kind though.

the question is why all four indices updated in the execution of SPI_execute_plan()? 
I think there should only one index, that is ind_a4 be updated, how to avoid other three indices updated?
thanks!
