I'm not sure how applications tell the kernel whether they are
interactive or background (or even if they do, at all), but you can
set the kernel's preference for this in the kernel configuration.
If you're not comfortable recompiling a new kernel, though, then
you're out of luck.
At any rate, you should look more thoroughly for problems with your
database before blaming the kernel for something.
