Yeah, fair. I think it depends on whether you think it is more likely
that people will (a) grep for PG_INT_MIN32 to find places where we do
overflow handling or (b) observe the close relationship between the
two constants on adjacent lines. Probably I should have waited for
comments before committing, but I figured we wanted to avoid hardcoded
constants and didn't think much further.
