void* isn't necessarily compatible with function pointers --- there are platforms where they're physically different widths, though possibly you'd never get PG to run on such hardware anyway. I'd be OK with declaring it as a more generic function pointer type, perhaps "void (*funcptr) ()". However, given that a cast is going to be necessary anyway, it seems like this is mostly useless churn... regards, tom lane
